I try to import a CSV file with Drupal 8 Migrate. One column contains a year value which I want to convert to a Drupal date field.
I try to do that with the following process statement using format_date plugin from Migrate Plus but something goes wrong:
process: field_fecha: plugin: format_date from_format: 'Y' to_format: 'Y-m-d\TH:i:s' settings: validate_format: false source: year
I'm not sure if Y is allowed as from_format value. But I also don't know what standard value uses Drupal 8 date field and what to put as to_format value.
