BigQuery > limitation in number of columns ?

[Julien]

Hi Community,

I'm trying to add a BigQuery datasource that contains 76 columns. It contains less than 100 rows.

AppSheet refused it so I tried with less columns. I was able to add a BQ with 40 columns. It fails with 50 columns.

Is there such a limit ? Or is there something I'm missing ?

Thanks a lot for your help !
