I am trying to fetch invocation id of an Azure Function using the app insights query:
requests
| project
id,
operation_Name,
operation_Id,
cloud_RoleName,
invocationId=customDimensions['InvocationId']
| where cloud_RoleName =~ 'appname' and operation_Name =~ 'Gen'
And The result table shows no value for invocation id:
Am I missing something? Please let me know in the comment If I can add more information. Thanks.
