Sometimes Data Source or Destination APIs don't correctly handle errors, and can only report to Flatly something vague like "Internal Error".
​
These errors simply mean something went wrong in that third-party app's server or API.

Usually, these errors resolve on their own after some time has passed (usually minutes, not hours).

If your jobs continue to fail with 500 Internal Server Errors for more than an hour, please start a live chat with us via the Help Desk.
