But I receive this error:

This means that the on_error setting is not working. When I try to insert a million records, this becomes extremely annoying and counterproductive.
When we specify that on_error should be ignored, any type of error including data type inconsistency, check constraint inconsistency, foreign key inconsistency, etc. should be ignored and Postgres should move to the next record and not fail the entire bulk operation.
While the would be a possible definition to implement what actually is implemented is:
"Specifies how to behave when encountering an error converting a column's input value into its data type."
