I am successfully migrating the content from Drupal 7 to Drupal 9. However, I am getting some extra non-breaking spaces I'd like to remove.


I tried using a basic str_replace plugin, but that doesn't work.


What am I doing wrong? What else should I look into?

    Have you confirmed that string exists in the source data?

By taking a look into the StrReplace class I see that you are missing the source key, which should be the name of the field/column/whatever you are importing from.

If it does not work, try to also remove the "regex" key and if it still does not, try to use a simpler search, to ensure that the problem does not lie with your data.
