Error in RichTextPreValueController: Object reference not set to an instance of an object
After several days of work, I've just finished updating Umbraco from v7 to 8.18.8.
My site seems to work fine, but everytime I open any node in the backoffice I get an error screen with this message:
Unhandled controller exception occurred for request '"http://localhost:52534/umbraco/backoffice/UmbracoApi/RichTextPreValue/GetConfiguration"'
System.NullReferenceException: Object reference not set to an instance of an object.

Does anyone knows what is happening? Should I ignore it? In that case, is there any way of hiding this message?
The problem was with the TinyMce package configuration.
Basically, the update of Umbraco also does an update of this package, which is the one that manages the RichText control that was causing the problem. The issue here, and I think this is a problem with the Umbraco update which they should solve, is that the update of the TinyMce doesn't update the TinyMce configuration file.
So, at the end, you would end with an old configuration file with plenty old stuff that is broken since they have changed that configuration system with every update of the package.
I found the tinyMce config file in config/tinyMceConfig.config.
I copied the content of this vanilla file over my file in my project.
Rebuilt and it worked.
In my case I did not have any specific configuration in the tinyMceConfig apart from the basic that comes with the installation, your case might be different.

Hi @danimarpe, did you manage to solve this? I am seeing the same issue after migrating from v7 to v8.
Actually, I did.

What I did to solve the problem:
config/tinyMceConfig.config.In my case I did not have any specific configuration in the
