PutDatabaseRecord fields don't map database colums

[#1]

Hi, im trying to upload a CSV to a RedShift database using GetFile->PutDatabaseRecord

i'm getting this error:

PutDatabaseRecord:

CSVReader (my file got headers, this way and not hardcoding the schema makes everything more easily scalable):

Null string: NULL

CSV:

A,B,C,D,E,F,G,H,I
2020-01-15,AX,COD245,NO,PASS,R,,,
2020-01-15,AX,COD235,YES,PASS,R,,,

Table with same fields names.

Any idea what i'm doing wrong? Is there any way to look for the query it's making, that will make this more easy to debug.

Thank you!

Solved, PutDatabaseRecord gives you mapping error if the table doesn't exists or if you don't have permissions, hours fighting against the columns names and it was a database problem.
