Anything else?

No response

looks like the use of max_size rule trigger the ErrorException, removing it seems okay

[kenjis]

You set max_size[upload_file_photo.2048], but the usage of max_size is like max_size[field_name,2048].

[hurtsky]

You set max_size[upload_file_photo.2048], but the usage of max_size is like max_size[field_name,2048].

Thank you!

This error message is not friendly, and it is a bug.
I sent a PR to fix it: #6261

might related to this, I just did some testing with mime_in rules, if the developer accidentally put the , to . it will throw same error. I'm not checking all the file validation rules, but might be the others rules also have this kind of error message
