Copy Activity Fails but shows as successful

[gkocev]

Hello,

We have a pipeline with ForEach activity that loops through a meta table to pick list of tables to load via Copy Activity. Up until now (for about 6-7 months) everything was working smoothly. For the past 2-3 days some strange behavior occurs:  random Copy Activites show an error in the output json: 
"Error": { "errorCode": 2012, "message": "Object reference not set to an instance of an object.", "details": [], "isRetriable": false, "retryBackoff": false }.

The strange thing is that despite the error, the respective table is loaded successfully, the Activity shows Success complete(which prevents the Retry to trigger), but activities that are connected to the OnFail of the Copy activity are triggered. 

Restarting the pipeline for the specific tables that "failed" runs without issue.

Has anyone else expirinced such situation and potentialy solved it? 

Thanks!

Hi @gkocev, 

It appears there is a service issue right now, there's been a handful of posts about this, example: https://community.fabric.microsoft.com/t5/Pipelines/Pipelines-and-pipeline-steps-return-wrong-status...

On the Fabric support page, Americas is currently listed sa having degraded service: https://support.fabric.microsoft.com/support/

I recommend submitting a ticket so Microsoft can see the full scope of the problem and get working on a fix.

Hi @tayloramy ,

Thanks for your response. This night everything ran ok, so probably as you advised there was some temp issue. Will see how it goes from now on 🙂
