Redshift COPY command delimiter not found

Question

I\'m trying to load some text files to Redshift. They are tab delimited, except for after the final row value. That\'s causing a delimiter not found error. I only see a way to s

From my understanding the error message Delimiter not found may be caused also by not specifying correctly the COPY command, in particular by not specifying the Data format parameters https://docs.aws.amazon.com/redshift/latest/dg/r_COPY.html

In my case I was trying to load Parquet data with this expression:

COPY my_schema.my_table
FROM 's3://my_bucket/my/folder/'
IAM_ROLE 'arn:aws:iam::my_role:role/my_redshift_role'
REGION 'my-region-1';

and I received the Delimiter not found error message when looking into the table stl_load_errors. But expressed in this way:

COPY my_schema.my_table
FROM 's3://my_bucket/my/folder/'
IAM_ROLE 'arn:aws:iam::my_role:role/my_redshift_role'
FORMAT AS PARQUET;

solved my problem and I was able to correctly load the data.
