Error calling Logic App HTTP Endpoint
Hello,
I have an Azure Data Factory Pipeline containing a foreach loop containing a Web Activity that triggers the HTTP Endpoint of a Logic App.
This worked flawlessly for months. A few weeks ago an error occured for the first time without any previous changes to the configuration:
Operation on target [foreach activity] failed: Activity failed because an inner activity failed; Inner activity name: [web activity name], Error: Error calling the endpoint 'https://prod-25.westeurope.logic.azure.com'. Response status code: 'NA - Unknown'. More details: Exception message: 'NA - Unknown [ClientSideException] Invalid Url:[Logic App URL]. Please verify Url or integration runtime is valid and retry. Localhost URLs are allowed only with SelfHosted Integration Runtime'.
Request didn't reach the server from the client. This could happen because of an underlying issue such as network connectivity, a DNS failure, a server certificate validation or a timeout.
I did a quick google research and came to the conclucsion, that it must have been some one-time "Azure hickup" due to some networking issues.
However, the same error occured again yesterday and today. So now apparantly it's not an one time issue anymore.
The weird thing is, the Web Activity is contained in a foreach loop and when the error occurs, only one of the executions fails and the others work just fine. So I suppose it cannot be some temporary network issue or something, since other executions of the same Web Activity calling the same Logic App, that take place within seconds of the one execution that fails, work perfectly fine.
This setup is used in a productive business intelligence environment where it is crucial that everything is up to date, which is not the case, if this error occurs. I would be really greatful if anyone could help me out with fixing this error, since my google research did not reveal any helpful input.
Thank you very much in advance!
Best regards,
Monica
