ArgumentCountError: Too few arguments on local copy

Hi pascalmortier,
Thanks for posting.
Please upgrade the module to latest stable 2.51 and clear cache. Afterwards retry the database dump.

Thank you for your quick response!
Not working after login... now I have WSOD after login.
No apache or php errors...

You need to clean your cache. If you are not able via frontend you can do it from backend composer or drush.
You may also do it with phpmyadmin, quick google search

@pedro-alves, i did it. Cache cleared by truncating all cache tables.

Great... and the database dump?

@pedro-alves : i make also a dump, not working
(and I cleared cache before making dump)

I see, let me take a look. I will post back.

Is the error exactly the same? Can you post here the error log.
Thanks

No I have a white screen, no errors. I make a dump with module backup_migrate and import local with sequel ace

I recommend updating those modules to latest versions also.
Because the spammaster version 2.51 fixed issues of older 2.xx and what you are reporting is not present anymore in 2.51.

Really make sure you clean the cache. The file spammaster.services.yml in spammaster module root folder should look like this on line 31,32,33

  spammaster.collect_service:
    class: Drupal\spammaster\SpamMasterCollectService
    arguments: ['@request_stack', '@config.factory']

I recommend these steps:
1. Upgrade those backup modules
2. If problem persists, check the server error logs to trace the error.

I updated to that version and spammaster.services.yml contains the spammaster.collect.service lines.
Maybe it has something to do with another module?
It is not the first time I get this error. Also on other projects.
I guess it is because spammaster tries to connect with the spammaster service but the domain name is not the same on my localhost.
I look further and if I find a solution, I will let it know.
Thanks a lot for your time and investigation!

No problem. Closing the issue.
Feel free to open another one if you discover something else.
