Expected argument of type "object, array or empty", "string" given

[nouha88]

Hello,
I have an issue.
After upgrading Prestashop to 1.7.8.7, once I open Invoices, it works fine at first.
Then suddenly I have this error: Expected argument of type "object, array or empty", "string" given.
I'm confused. I've tried to follow some of the solutions found on this forum and GitHub but it's weird, it's that it could at this very moment work well but suddenly then I get the error mentioned.
Did that happen to anyone of you?
What should I do?
Thank you.

It's not working with prestashop 8.1, can't be installed on PS 8.1, is it possible to update it?

Thanks for sharing such a useful tool.

Hi @jamshidpour,

I had a look over it and the problem seems to be the fact that the module is not declared as compatible with PrestaShop 8. Other than that, it still works fine.

You can just do the following in order to make it work:
- download the latest archive
- unarchive it
- go into the fixconfigurationlang directory
- edit the fixconfigurationlang.php file
- replace line 44 ('max' => '1.7.99.99',) with the following: 'max' => '8.99.99',
- save the file
- archive the directory fixconfigurationlang directory

Once these steps are completed, you can try and upload the new archive. It should work at this point.

Thank you @Andrei H

As you told, it worked great after changing the config file.
