Online League File Import - Error 151 - How to actually troubleshoot?

the doctor · 08-04-2025, 12:30 AM

i have one team in my online league whose export is throwing the following error: error 151 // couldn't find contract offer's player id in db

i understand conceptually what this means. however, like most of the error codes, it doesn't provide enough information to make troubleshooting possible.

what can i do to try and resolve this?

Most commonly, this seems like a case where the may have been something corrupted in their local file. I would recommend as a first step to fully re-download the league file and try to export again. If you still have the error, if you can send us a link to the league file and send the export causing issues, we can investigate further.

I'm having this happening too. Think it's a posted player from an international league.

Thanks, yes, there may be an issue with posted players. We'll investigate and fix
