Hi @PriyaSinha-9031,
Can you share more details regarding how you invoke this "ADO REST API" inside the Azure Function?
If I understand you managed to query the api using PowerShell but it is not working when you try inside a Azure function.

The error that you posted seems to be a PowerShell error.

what type of authentication is this api using? How do you invoke inside the azure function?

@PriyaSinha-9031 ,

Thanks for reaching out to Q&A.

First you need to make sure that the powershell module that you are using is compatible with Poweshell core. Minimum supported powershell version in Azure functions is 6 but we recommend 7 as it is the latest version. So I would suggest you to test the module in powershell core and then deploy it to Azure functions once you have confirmed it's working in PS core as expected.

I would suggest you to provide more details about the exception (full stack trace along with the line of script that throws exception) so that it would be helpful to provide a solution. Looking at the exception type Microsoft.PowerShell.Commands.WriteErrorException, it appears that you are trying to write something to a file system. Please note that, writing to a file system might be restricted in Azure functions as it is a sandboxed environment. Please refer to this document for more details.

Hi Guys, Thanks for your response.
I was getting this error entire day on Friday. I ran it today and is not throwing the exception anymore.
Do you know if there was any downtime in Azure function, any kind of deployment /change in functionApp which could affect this ?
I am really curious to know as I spent almost half of the day trying to figure this out

@PriyaSinha-9031 , Please check the Diagnose and solve problems blade in the Function portal. Run "Function app down or reporting errors" detector to get any information about downtime/exceptions
