"az containerapp env telemetry app-insights set" fails to set connection string

[mhurst-microsoft]

Describe the bug

Executing the az containerapp env telemetry app-insights set command as per the documentation results in the response:

{
"connectionString": null,
"enableOpenTelemetryLogs": true,
"enableOpenTelemetryTraces": true
}

with the connection string not being set and no indication of the reason.

Related command

az containerapp env telemetry app-insights set -n env-album-containerapps -g album-containerapps --connection-string "" --enable-open-telemetry-traces true --enable-open-telemetry-logs true

Errors

No error message is generated - the command doesn't work as expected.

Issue script & Debug output

Editing the debug output for privacy is non-trivial; please provide a method to produce debug output with sensitive data removed.

Expected behavior

The command should set the connection string for application insights in the ACA environment.

Thank you for opening this issue, we will look into it.

I reread the documentation and found that null is actually the expected value in the response for the connection string. So this is probably no-longer a bug. That being said - it would be useful if the command indicated success and possibly indicated that null is a substitute value to avoid the type of misinterpretation that occurred with me.

Hi @mhurst-microsoft
Thanks for suggestion.
Yes, currently when you see "connectionString": null, it means the connection string has been set successfully.
Refer doc: https://learn.microsoft.com/en-us/azure/container-apps/opentelemetry-agents?tabs=azure-cli#azure-monitor-application-insights

Due to the sensitivity of the connection-string, you will not be able to see the detail values of the connection string when the command returns. The system will display it as null.

We will consider refine this behavior.
