GENERIC_INTERNAL_ERROR

Error message

Neither of encryptColumn or encryptTable present. We should never hit this

What it means

Defensive sentinel at the end of DWRF encryption metadata resolution: neither table-level nor column-level encryption information is present, which the code treats as an impossible state for a table flagged as encrypted.

Solutions

1. Check the table's encryption properties for malformed values
2. Re-create the table with valid encrypt_table or encrypt_columns settings
3. Report as a connector bug if the properties appear valid
