I am loading a CSV in BigQuery and since today it is giving me the error:
‘Field name ‘”LEVEL”‘ is not supported by the current character map. Please change your field name or use character map V2 to let the system modify the field names.’

LOAD DATA OVERWRITE `green-gearbox-217510.DATA.INVERSION`
FROM FILES ( format = 'CSV' ,uris = ['gs://landing/INVERSIONES.csv']);

I have even tried it with a file that I used 4 weeks ago, and where it did not fail before, it is now failing with the same message. It’s as if BigQuery has made changes to your environment.

The SQL I use is not very scientific, the schema automatically detects it because each CSV field is well defined:

I don’t understand what is happening in BigQuery.

Any suggestions to resolve this error?
