This message appears after checking "Generate CRUD" and press save: array_filter(): Argument #1 ($array) must be of type array, null given

[77ghjr77]

log content： array_filter(): Argument #1 ($array) must be of type array, null given {"exception":"[object] (TypeError(code: 0): array_filter(): Argument #1 ($array) must be of type array, null given at /var/www/vendor/backpack/crud/src/app/Library/CrudPanel/Traits/SaveActions.php:52)

In fact, after reloading the web page, I found that the program was executed successfully. How can I solve it please? (I installed it normally and did not manually modify the program.)

@tabacitu Sorry, I forgot to say. I'm building the backup in a docker container, not sure if the issue is related to this.

Also I am attaching pictures that may be relevant to this issue.

I think this is the same issue as https://github.com/Laravel-Backpack/CRUD/issues/2708

@77ghjr77 can you provide me the generated controller when you got the error ?

Cheers

@pxpm Thanks.

Unfortunately we couldn't replicate the issue... Please, if you get this error again, let us know how to better reproduce it... A video recording with the Chrome console would be great too - maybe that would provide more info.

If anybody else gets it, please let us know and we'll reopen... but until then... we have no idea what to do here, sorry 🤷‍♂️

We'll close this as there's nothing we can do right now. But... I have a feeling this isn't over. Let us Know.

Cheers!
