Azure function, Incompatible Node.js version (v18.15.0)

Question

Azure function, Incompatible Node.js version (v18.15.0)

Dataholic 80

In vscode, starting a debug a Azure Function and error message,

Incompatible Node.js version (v18.15.0). Refer to our documentation to see the Node.js versions supported by each version of Azure Functions: https://aka.ms/functions-node-versions

The Azure function is Model 3. I checked above link, Model 3 should support V18.X.

How can fix this issue?

@Dataholic Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I understand that you are facing an issue in your dev environment with the NodeJS Function APP in VSCode.

As you rightly mentioned, the v3.x FunctionApp Programming Model supports 18.x Nodejs version.

The following table shows each version of the Node.js programming model along with its supported versions of the Azure Functions runtime and Node.js.

More Info here.

Could you please share the detailed error message and the screenshot of the error message ?

Please run the node -v command and share the output here.

Please try setting WEBSITE_NODE_DEFAULT_VERSION in your local.settings.json file and check if that helps. This property sets the version of Node.js to use when running your function app on Windows and you can set to any of the supported version as per your function app Node.js targeting version.

Awaiting your reply.

local.setting.json. I modified the initial responding. But the update doesn't show. I add the file here again.

{   "IsEncrypted": false,   "Values": 
 {     
"WEBSITE_NODE_DEFAULT_VERSION": "~18",     "FUNCTIONS_WORKER_RUNTIME": "node",     "SynapseCoreBlob": "UseDevelopmentStorage=true",     "BlobStorageConnectionString":"MyStorageURI"   
  }

@Dataholic Thanks for getting back. Could you please follow the below action plan and check if that helps ?

1.Run the below commands and share the output:

func version

node -v

2.Please add the below in your local.setting.json file
FUNCTIONS_EXTENSION_VERSION to ~3 and check if that helps.

@navba-MSFT Thanks for your continued support!

Following the instruction, but still receive the same error. May be there is something I need to clear or restart?

Below two return values are the same before and after I added

"FUNCTIONS_EXTENSION_VERSION":"~3",

func version---4.03971

node -v---18.15.0

Here is my local.settings.json

{ "IsEncrypted": false, "Values": { "WEBSITE_NODE_DEFAULT_VERSION": "~18", "FUNCTIONS_EXTENSION_VERSION":"~3", "FUNCTIONS_WORKER_RUNTIME": "node", "SynapseCoreBlob": "UseDevelopmentStorage=true", "BlobStorageConnectionString":"MyStorage" } }

@Dataholic Thanks for confirming. I see that you are using an older version of Function core tool version. Please uninstall and reinstall the most recent version of Function core tools runtime and that should fix this issue. Please see this: https://github.com/Azure/azure-functions-core-tools#installing

While I used the most recent version of function core tools runtime version it worked fine.

These are the versions which I am using:

❯ func --version

4.0.5198

❯ node --version

v18.16.1

User's image

So it works with newer CoreTools and v18 of Node. Hope this helps.

@navba-MSFT Thanks for your info! I clicked on view --- then selected "Azure function: uninstall...." Then reinstalled function core tools". But still received same error. May be there is something wrong with my local.settings.json?

When I click on Run --- starting debugging.. then I received the error as before.

However if I right click on function --- HttpTrigger1 and select "Excite function now...", I will receive the error of "Failed to connect. Make sure your project is running locally."

strange...

@Dataholic Thanks for getting back. Could you please make sure your node and func runtime versions are same as mine ?

❯ func --version

4.0.5198

❯ node --version

v18.16.1

Once you confirm the above, Please create a new function sample application from your VS code / VS and check ?
