Custom fields in Drupal 7 not migrating to Drupal 10 due to text filtering error

@seumas.gagne, The Drupal Core issue queue is not the ideal place for support requests. For migration, you will get better responses from the migration community in the #migration channel of Drupal Slack → . There are other support options listed on our support page → (Community > Support at the top of Drupal.org). You may get better replies in one of those places.

it's not the actual data records, it's field instances, some fields have text_processing set to yes, some has set it to no, the system has no idea what to migrate to , open field ui in d7 and rectify the situation by setting all of the text procesisng yes if that's what you need.

I just recalled this, https://www.drupal.org/docs/upgrading-drupal/upgrading-from-drupal-6-or-... →
