[BUG] Get-PnPTermGroup do not work with app permissions.

[stvpwrs]

Reporting an Issue or Missing Feature

When using Get-PnPTermGroup with a connection created with app permissions the cmdlet fails with an out of index error or hangs an Azure Automation Runbook.

I believe this also impacts Get-PnPTerm.

Expected behavior

I expect this to return a collection of Term Groups.

Actual behavior

I have gotten a number of errors depending on how I try to call the code, but the example below just times out and suspends an Azure Automation Runbook with no error capture.

Often Value cannot be null. Parameter name: path but I believe this is because variables used to try and capture the result just time out and get assigned null.

I have also received Specified argument was out of the range of valid values. Parameter name: index when attempting to pass the result of Get-PnPTermGroup in a variable.

@stvpwrs have you given the app registration the required application permissions? e.g. TermStore.Read.All or TermStore.ReadWrite.All

[stvpwrs]

@CallumCrowley Yes the app has proper permissions.

Hi @stvpwrs

Have you tried adding the SharePoint principal as term store admin?

Closing due to lack of response.

Hello, sorry for the lack of response here, this issue slipped my mind. I think we should leave it closed, I just ended up not using an automation account for this.

There was so much odd behavior with the automation account that the local client didn't have, I just stopped trying to troubleshoot it. I will say that all of the auth and permissions were correct and all the code would correctly run locally, just not in an automation account.
