Hi @Hamza User?,
I searched the logs for Job Group ID 18512018, but the full error is pretty much the same:
"Error getting status of job 30068777 (jobGroupId 18512018) - HTTP BigQueryJobFailed: BigQuery job failed: {errorMessage=Not found: Connection [connection_identifier] at [2:1], label=general-bigquery-job-runtime-exception, job-group-id=18512018} - 500"
For reference, here is an explanation of the 500 error code.
I have never encountered this error message before. Are able to comment on the redacted connection identifier? To what does this pertain, etc.?
I broadened my search to include all jobs for this flow. It has only succeeded once: on February 28, using Dataflow instead of the BigQuery running environment. Furthermore, I see that all jobs that were run on BigQuery have failed; whereas, jobs that ran on Dataflow typically have succeeded.
With this in mind, I recommend verifying the Required Dataprep User Permissions (esp. the Connection Permissions - BigQuery section and BigQuery-relevant entries in the Feature Permissions section). In addition, you may wish to try disabling optimization -- at least for this flow -- in the Flow Optimization Settings Dialog. This will force the job to run on Dataflow.
If ineffective, then best is to file a support ticket by emailing support at trifacta dot com. Please include a link to this thread for reference, as well as the exported flow corresponding to Job Group 18512018. Note: no input or output data is included with a flow export.
I hope this helps!
Cheers,
Nathanael
