Inserting <script> into source code

[dmayzhanov]

Hi, @emilianotisato

When saving source code with embedded <script>, an error appears in the console. A screenshot is attached.
The config contains the settings 'extended_valid_elements' => 'a [id | class | href | target | title | uk-toggle], script [src | async | defer | type | charset | class]'

Hi @dmayzhanov , can you please add steps to reproduce this error?
Thanks

Hi @emilianotisato,

1. Open the source code of the article in the editor
2. Add any script there. You can even empty "<script> </script>"
3. Click on the save button and get the error "Cannot read properties of undefined (reading 'indexOf')"
