The Drupal\webform_dropzonejs\Element\WebformDropzonejs::preRenderDropzoneJs uses $element['#extensions'] = $element['#upload_validators']['file_validate_extensions'][0] ?? ''; to determine valid file extensions. This doesn't seem to be valid anymore in newer versions of webform/Drupal.
https://www.drupal.org/project/webform/issues/3465838 handles this as follows:
- $validators = ['file_validate_extensions' => ['csv']];
+ $validators = ['FileExtension' => ['extensions' => 'csv']];
We need to do the same.
Update to a recent version of core/webform and try to drag and drop to upload a file. Upload fails no matter what the file type is. Futher, clicking "select files" doesn't even allow selection of any files because it thinks there are no valid extensions.
Update extension validation.

mrweiner commentedThere are issues with the MR because 1.0.x is somehow behind 1.0.3. But this is a one-line change so should apply cleanly.

arno_vghThanks for the MR it works with the default version.
This patch resolves the issue when using version 1.0.3 in combination with the chunked file upload support introduced in issue #3549965. This is based on the code shared in comment #11 on #3499051).
