I have googled and read articles from the community, but I still can't solve this.

This is my job profile, https://community.dremio.com/uploads/short-url/edtC2D5EKmhPJViVSEo4V5RbGAe.zip

Your 1st field (the field with index 0) has 1 or more values exceeded 32000 bytes, which is Dremio's size limit for a data value.

You probably need to find and exclude that row of value, or try to cast the column to VARCHAR
