How to resolve ReactView errors in Edge browser when loading resource blades in the portal

Steve Giordano 0

I've been having intermitent issues with resource blades opening in the portal. Below are the summaries of the error logs I am getting. I refresh the browser page and it then loads.

{ "shellProps": { "sessionId": "496e3b70739049ceb1b10b704cba0bbe", "extName": "Microsoft_AAD_IAM", "contentName": "TenantOverview.ReactView" }, "error": { "details": "Manual require of the following modules failed; ["Microsoft_AAD_IAM/Tenants/Overview/MonitoringTab/MonitoringTabStrings.resjson" : {Error: Couldn't load "Microsoft_AAD_IAM/Tenants/Overview/MonitoringTab/MonitoringTabStrings.resjson"; error code 0}];", "message": "Content failed to load.", "error": { "data": { "details": "Manual require of the following modules failed; ["Microsoft_AAD_IAM/Tenants/Overview/MonitoringTab/MonitoringTabStrings.resjson" : {Error: Couldn't load "Microsoft_AAD_IAM/Tenants/Overview/MonitoringTab/MonitoringTabStrings.resjson"; error code 0}];", "message": "Content failed to load.", "capturedErrors": [] } }, "code": null }}

{ "shellProps": { "sessionId": "afded3c45786457db4e36a3d5181cb9b", "extName": "HubsExtension", "contentName": "BrowseResourceGroups.ReactView" }, "error": { "details": "Manual require of the following modules failed; ["HubsExtension/Browse/Blades/BrowseResourceGroups.ReactView" : {Error: Couldn't load "HubsExtension/Browse/Blades/BrowseResourceGroups.ReactView"; error code 0}];", "message": "Content failed to load.", "error": { "data": { "details": "Manual require of the following modules failed; ["HubsExtension/Browse/Blades/BrowseResourceGroups.ReactView" : {Error: Couldn't load "HubsExtension/Browse/Blades/BrowseResourceGroups.ReactView"; error code 0}];", "message": "Content failed to load.", "capturedErrors": [] } }, "code": null }}

Hey Steve, it looks like the portal is intermittently failing to load the ReactView modules for your blades (for example, the MonitoringTanStrings.resjson or the BrowseResourceGroups.ReactView), then succeeds on a refresh. This kind of behavior usually points at one of three things in Edge:

Corrupted or stale browser state

Blocked or timed-out HTTP requests for the portal’s JS modules

Browser-specific quirks or extensions getting in the way

Here’s what you can try first to rule out the usual suspects:

Open the portal in an InPrivate window (Edge)

Disable all browser extensions and test again

Clear the portal cache: • In the portal, click Settings (gear icon) → “Clear cache” • Then clear full browser cache & cookies (Edge Settings → Privacy, search, and services → “Choose what to clear”)

Make sure you’re on the latest Edge build with JavaScript and hardware acceleration enabled

If you’re on a corporate network or behind a proxy/firewall, safelist these endpoints on port 443: • portal.azure.com / *.portal.azure.com • hosting.portal.azure.net • login.microsoftonline.com • management.azure.com

After clearing state, reload the blade and capture a HAR trace (F12 → Network) to see if any scripts return “result code 0” or 403/401 errors

If it still misbehaves, let’s gather a bit more info:

Which exact Edge version are you seeing this on?

Does it repro in Incognito/InPrivate or when you disable all extensions?

Does it happen in another browser (Chrome/Firefox) or only in Edge?

Are you behind a corporate proxy or private endpoint that might be blocking scripts?

Is it only specific blades (AAD IAM or Resource Groups), or all blades?

Answering those will help narrow it down.Hey Steve, it looks like the portal is intermittently failing to load the ReactView modules for your blades (for example, the MonitoringTanStrings.resjson or the BrowseResourceGroups.ReactView), then succeeds on a refresh.

I followed the steps you outlined above and I'm still seeing the issue in an InPrivate window. The same error occurs when I use Chrome and Incognito in Chrome. Running the Developer tools, I see type "script", "fetch", "xhr" where the errors occur. Here are some of the request URLs if that helps.

https://hosting-ms.portal.azure.net/websites/Content/Dynamic/kSu_YvjnVA8D.js?retryAttempt=1.7677643502505407

Here's the error in the browser:
{ "shellProps": { "sessionId": "76f557c8b02842a0b89e2b26def22e57", "extName": "WebsitesExtension", "contentName": "AddOrEditRevisionContainer.ReactView" }, "error": { "details": "Manual require of the following modules failed; ["WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.ReactView" : {Error: Couldn't load "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.ReactView"; error code 0}];", "message": "Content failed to load.", "error": { "data": { "details": "Manual require of the following modules failed; ["WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.ReactView" : {Error: Couldn't load "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.ReactView"; error code 0}];", "message": "Content failed to load.", "capturedErrors": [ { "message": "Unhandled Promise Rejection", "metadata": { "area": "ReactInternalErrorHandler", "error": { "stack": "Error: Manual require of the following modules failed; ["WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher" : {Error: Couldn't load "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher"; error code 0}];\n at we (https://reactblade.portal.azure.net//Content/Dynamic/6h5DPMCv01PD.js:1:3404)\n at l (https://reactblade.portal.azure.net//Content/Dynamic/6h5DPMCv01PD.js:1:9766)", "message": "Manual require of the following modules failed; ["WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher" : {Error: Couldn't load "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher"; error code 0}];", "data": { "moduleId": "require 9", "status": 0, "failedModules": [ { "name": "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher", "moduleUrl": "https://hosting-ms.portal.azure.net/websites/Content/Dynamic/kSu_YvjnVA8D.js?retryAttempt=1.7677643502505407", "message": "Couldn't load "WebsitesExtension/Views/ContainerApp/CreateRevision/Container/AddOrEditRevisionContainer.DataFetcher"; error code 0", "status": 0 } ] }, "name": "Error" } } } ] } }, "code": null }}

I refresh the browser page and it loads.
Which exact Edge version are you seeing this on?

Does it repro in Incognito/InPrivate or when you disable all extensions? Version 149.0.4022.69 (Official build) (64-bit)

Does it happen in another browser (Chrome/Firefox) or only in Edge? - yes Chrome/Icognito

Are you behind a corporate proxy or private endpoint that might be blocking scripts? - no, home wifi, no fw

Is it only specific blades (AAD IAM or Resource Groups), or all blades? - all blades - will happen on any blade I select randomly.

Not sure if this helps - it's a lot of info and hope it's readable. :) Network Dev Tools shows Name "extensiontelemetry", url is https://portal.azure.com/api/extensiontelemetry below is the request header if it helps.

I think the log shows the Portal didn’t fetch the UI files for those blades. Azure Portal can hit this kind of load failure on the client side, and a new tab or InPrivate gives the session a clean start, so the blade opens.

Hi ,

Thanks for reaching out to Microsoft Q&A.

This is typically a client-side loading issue in the azure portal (ReactView modules failing to load), not a backend resource problem. In Edge, it is usually caused by cached/corrupted portal assets, blocked scripts, or extension interference. Fix it by doing a hard refresh (Ctrl+F5), clearing browser cache/storage for the portal, and disabling extensions (especially ad blockers or security plugins). Also ensure 3rd party cookies and local storage are not blocked, and try opening the portal in InPrivate mode to validate. If it still happens intermittently, it is often due to transient CDN/module load failures in the portal itself, and there is little to fix beyond retrying or switching to another browser session.
