Hello With the new load_data_by_post, I'm not able to upload a JSON file and I have this error "Cannot load CSV data with a nested schema". Sounds like the job expect a CSV not a JSON file so do I need to do something special ? And I tested on the web client with my data/schema and it works fine, here the [schema](https://gist.github.com/Falydoor/200477dee839c84afc2a) and the [data](https://gist.github.com/Falydoor/cc4fc2a28a91e86cefb5) in case you wanna test. Regards
