What it means
The file has columns the contract does not read. The message lists them.
What to do: If one holds a field you need, add its name to that field’s column_map list in your adapters folder. Otherwise ignore it.
Decide whether the extra column matters
Read the warning's column list and inspect the export header. An unused comment column may be irrelevant to your question. A person or event identifier you intended to analyse needs a mapping. Check what the column contains before discarding it to silence the warning.
Change the adapter deliberately
The reference's Jira example adds the physical authorId header to the canonical employee field:
employee_id: [author.accountId, authorId]This line belongs in the copied contract's column_map. If the field is required, update required_fields as described in the full adapter procedure, set ADAPTERS_DIR, and validate again. Inspect a known row to ensure that the newly consumed column represents the intended field.
