TypeError: Cannot access offset of type string on string

aaron.ferris → made their first commit to this issue’s fork.

Seems the widget options default value is '', so on first add of the field we are trying to access keys/values that don't exist yet.

Raised an MR.

Screenshots with change, with multiple rate widgets on a view.

Thank Aaron, it works.
+1 for RTBC

This error is occurring again in Drupal 10.
I cannot use a second "rate widget view field" within a view page. I get the following error.

TypeError: Cannot access offset of type string on string in Drupal\rate\Plugin\views\field\RateWidgetField->render() (line 228 of /chroot/home/---/---.com/html/modules/rate/src/Plugin/views/field/RateWidgetField.php).

@digitalore works as I would expect here, what version of Drupal?

10.2.6 here, article content type with 2 rate widgets, a view of articles with both rate widgets configured.

As per screenshot.
