Using Views Date Format SQL options on custom date fields

Works for me with Drupal 9 if I patch with #3 then #18.

Hi I am using D9.5 and here is the patch that works for the custom date fields (I combined the #18 and #3 basically, but there were some tweaks needed as #18 was not applying cleanly). It works well to apply the custom SQL format to the custom field. Thanks

I'm using D10.1 and patch #22 is working as expected, however, I'm getting the following warning:

Trying to access array offset on value of type null views_date_format_sql.views.inc:34
Undefined array key "field" views_date_format_sql.views.inc:34

The attached patch fixes this problem.

Thanks for the update @lolgm

@MukhtarM I'm having a problem with the patch.
It seems to me that something went wrong with the combination of patch #3 and #18.
The code below is referencing a plugin that does not exist in the current patch.

if (!empty($field['field']['id']) && $field['field']['id'] === 'date') {
  $field['field']['id'] = 'views_date_format_sql_date';
}

Could we remove this one?

@lolgm Actually the patch didn't included the new plugin file (my bad :( ). Corrected it and included your changes also. thanks.

Patch in #26 applies cleanly to 3.x-dev and fixes the problem, Drupal 10. Thanks @MukhtarM!
