Hi @max_alpha!
Seems that there's a closing quotation missing in the file you're loading. Perhaps, there is an example that's too long that MySQL cannot handle it (greater than your character limit).
You can start by validating your samples to investigate your database and see if something looks suspicious (e.g. JSON data that doesn't end with }) and was truncated.
If that's the case you can then do the following:
- try increasing the character limit of your columns
- add a check in a custom recipe that warns you if an example is too long
