Today we have released a new version of MySQL extractor in which a bug was present.
It caused errors in the UI:
Decoding JSON response from component failed: Syntax error
It also affected jobs of this extractor. Although the jobs seemed to finish successfully, they didn't process any data.
The flawed version was released at 12:14 and reverted at 15:09 CET.
UPDATE:
Another version deployed on May 12th 9:25 introduced another bug, which affected certain queries, resulting in error message:
DB query failed: Trying to access array offset on value of type null
We have reverted this release today on May 13th 11:26.
We sincerely apologize for the errors. A postmortem reports will follow with further details.
