Connect-AzContext throws the given key 'WriteWarning-System.EventHandler' was not present in the dictionary

I have following command for connect Azure with user assigned managed identity in Azure Functions (we have 18 functions running at same time). But got exceptions in some invocations.

Connect-AzAccount -Identity -AccountId $ENV:AZURE_CLIENT_ID

Thanks for reporting the issue. I'll follow up with it.

Thank you, @isra-fel

I tried to update the command to follows in function script but got following errors when trying to read KeyVault.

if ((Get-AzContext).Count -eq 0) {
    Connect-AzAccount -Identity -AccountId $ENV:AZURE_CLIENT_ID
}

This is the authentication commands in profile.ps1.

if ($env:MSI_SECRET) {
    Connect-AzAccount -Identity -AccountId $ENV:AZURE_CLIENT_ID
}

I added the command to each function as it randomly throws the following errors and failed to read KeyVault. However, with adding Connect-AzAccount -Identity -AccountId $ENV:AZURE_CLIENT_ID directly, it throws the errors The given key 'WriteWarning-System.EventHandler1` in the issue...after adding the checking line, it failed to read KeyVault randomly again...

We have 16 timer trigger functions within one function app running every 5/10/15 minutes, and 3 queue trigger functions might run at same time. Follows are related configurations. FUNCTIONS_WORKER_PROCESS_COUNT = 10 FUNCTIONS_WORKER_RUNTIME = powershell FUNCTIONS_EXTENSION_VERSION = ~4

I have same issue here. Looks it randomly showed up.
