Background of the issue:
I am encountering an issue when using WPML with ACF custom Gutenberg blocks inside widgets. I have widgets that include Gutenberg blocks (custom ACF-Gutenberg blocks) with a Repeater field containing radio buttons and a select field. I logged the $string variable during the process. Its value was: {"field_cta_buttons_button_type":"static_auth_buttons","field_cta_buttons_button_style":"primary","field_cta_buttons_static_auth_button":"registration"}.
Symptoms:
When I try to save changes to these widgets, I encounter the error: 'strlen(): Argument #1 ($string) must be of type string, array given' on the first save attempt. If I click the 'Update' button a second time, the changes are saved successfully. Additionally, when I remove all blocks from a widget and try to re-add the block, I get a different error: 'md5(): Argument #1 ($string) must be of type string, array given'.
Questions:
How can I resolve the error when saving changes to widgets with ACF-Gutenberg blocks?
What causes the md5 error when re-adding blocks to a widget?
set for the acf fields of this block 'wpml_cf_preferences' => 0, deleted the blocks from the widgets, and then added new ones, and when I try to save I get the same error
