Drupal 8.x

Hi,

I am trying to set up Module Builder as my application would be similar to an LMS and hence, needs a lot of custom module.

However, Module builder always fails during code scan with below error:

otice: fwrite(): write of 62 bytes failed with errno=22 Invalid argument in DrupalCodeBuilder\Task\Collect\CodeAnalyser->sendCommand() (line 163 of D:\xampp\htdocs\vendor\drupal-code-builder\drupal-code-builder\Task\Collect\CodeAnalyser.php)

Drupal 8.8.5

I have 2 fields data field_data and field_data_di_rientro
When I change the date of field_data, it must update the value of the field_data_of_entro field.

In form_alter I wrote this code
$ form ['field_data'] ['widget'] ['0'] ['value'] ['# attributes'] ['onchange'] = "this.form.data_di_rientro.value = this.value";

Since it does not update the second field, I inserted an alert on updating the field and it displays it
$ form ['field_data'] ['widget'] ['0'] ['value'] ['# attributes'] ['onchange'] = "alert ('OK')";
Where am I wrong?

I´m trying to group two fields in a table view but the following message appears : 

Competicion (one of the two fields): <!-- THEME DEBUG --> <!-- THEME HOOK: 'views_view_field' --> <!-- BEGIN OUTPUT from 'core/themes/stable/templates/views/views-view-field.html.twig' --> <a href="/node/443" hreflang="es">Trofeo Rectora</a> <!-- END OUTPUT from 'core/themes/stable/templates/views/views-view-field.html.twig' -->

and it doesnt works! Somebody know something about this?

Thanks all!

Sometimes, during development, it happened that the views gave a json problem.
Once, in an editable view, but I was able to understand that the problem was that it must not have the cache.
Other times, without understanding why, this happened in normal views by saving settings or simply adding fields to an already existing view. In these cases I solved it by going back to the previous backup.

But the reality is that I can't understand "what" should be avoided (apart from the conflictiong modules) in order not to get these problems.
