Drupal 8.x

Hello,

After Upgrading From Drupal 8.6 to 8.7, I am unable to attach files to nodes while already uploaded files works well. The error message I get when I try uploading is :

Hello,

I am getting this error after upgrading from Drupal 8.6 to Drupal 8.7

TypeError: Argument 3 passed to Drupal\views\EntityViewsData::mapFieldDefinition() must implement interface Drupal\Core\Field\FieldDefinitionInterface, null given,

While on dev site things went very well, on prod, this happen.

Any Idea ?

Thank you.

I have a basic Drupal 8 (8.7.0) site on a MAMP installation on a mac. When I try access /admin/modules/uninstall, the site redirects to /core/install.php. 

Any ideas on how to fix this?

Sorry if this is a silly question.

Is there a way to the [current-page:title] into the body of a content type I have tried the same thing which is in the meta tags but with no joy.

[current-page:title], [site:name], [node:title]

So what I would be looking for is something like this in the content type body:-

"Welcome to the [current-page:title] [site:name] we hope you enjoy your......."

Using Drupal 8.7.2

Thanks
 

All my websites cannot be edited after the update to 8.7.2 because drupal always tells me at EVERY listbox in every content type:

“The value you selected is not a valid choice.”

Even if I do not change the page and only click on save again this error is showing up.

Value of the Listboxes look like this:

1|text for the listbox

Please help. I do not know what to do.

There is no error showing up in the reporting area.
