We are facing Qlik sense application reload failure. We had no issues with this app's reload in the past and we are suddenly seeing this. The query runs in MySQL workbench with no errors.
We just had the same problem. I asked our MySQL guy to run the query directly on the DB and he found rows that had an end time of 24:00:00 which as a string is fine but as time is illegal. He updated those and that solved the issue.
