Update table through REST

Hi there,
I am trying to update my ACF table through WP REST API, without success.
After sending POST/PUT request, I get other fields updated, but table field disappears.

I found this error in log:
PHP Warning: urldecode() expects parameter 1 to be string, array given in /wp-content/plugins/advanced-custom-fields-table-field/acf-table-v5.php on line 380

which is

$value = urldecode( str_replace( '%5C', '%5C%5C', $value ) );
