The config schema for the filter plugin is missing. Because in recent Drupal versions filter configuration is validated, this makes it impossible to save a filter when the responsivewrappers module is installed.
Install a recent version of Drupal (10.3 for example), install the module.
Try to configure a filter with ckeditor enabled.
save the filter, notice the error:
Error message
'responsive_iframe' is not a supported key.
'responsive_iframe_pattern' is not a supported key.
'responsive_table' is not a supported key.
'responsive_image' is not a supported key.
Add the missing config schema

none, but the exported config will have TRUE and FALSE instead of 1 or 0.

My team was able to save the filter after applying the patch. Thanks!
Thank a lot, i confirm MR6 patch applies nicely on 2.0.1, uploaded it in patch format for convenience.
