REST API search can't return the Entity which one already in the Data Map

Question

REST API search can't return the Entity which one already in the Data Map

Mofei Zhuang 100 Microsoft Employee

My question is when I try to use https://learn.microsoft.com/en-us/rest/api/purview/datamapdataplane/entity/get?view=rest-purview-datamapdataplane-2023-09-01&tabs=HTTP this REST API to search an Entity, it always returns to me below error :

{"requestId":"af91b0e2-465b-462a-bb02-2c148699868d","errorCode":"RequestTimeout","errorMessage":"Request timed out. This could be a transient issue and you may re-run the operation following https://aka.ms/purviewdatamap408 troubleshooting guide. If it fails again continuously, contact customer support."}

I tried several times this error still here, it's not a transient issue.

And I can see this Entity from Purview Portal:

you can see the guid of this Entity is : 12c39433-db55-4a6c-a54c-8e820c2e2d74.

Hi Mofei Zhuang
It sounds like you're running into a persistent issue with the REST API for searching an entity in Azure Purview Data Map. That “Request Timeout” error can indeed be frustrating, especially if you've double-checked in the Purview portal and the entity is visible.

Here’s a few things you can try or consider:

Check API Limits/Throttling: Make sure that you’re not hitting any rate limits or throttling restrictions of the API. Frequent requests in a short period can sometimes lead to timeouts.

Entity Identifier: Ensure that you are using the correct GUID for the entity in your request. Even a small typo could result in the query failing.

Timeout Settings: If the API allows for a timeout parameter, you could consider adjusting that, if available, to see if a longer timeout helps.

Network Issues: Check your network connectivity as issues there can lead to timeouts as well. Try running the API request from a different network if possible to rule out any local networking issues.

Logs and Monitoring: If you have logging enabled, check the logs for any more detailed error messages or clues about why the timeout is occurring.

Troubleshoot Links: You mentioned the troubleshooting guide (https://aka.ms/purviewdatamap408); be sure to go through the steps outlined there, as they could provide insights specific to your environment.

If the problem persists after trying all the above, consider reaching out to Azure support with the requestId provided in the error message for deeper investigation.

In the meantime, could you clarify a couple of things:

Are you accessing the API from a particular environment (e.g., local machine, Azure function)?

What methods or headers are you using in your API call?

Have you made any changes to the entity or the Data Map configuration recently before this issue started?

Hope this helps you troubleshoot! Let me know if you have any further questions!
