"Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed" when submitting form with file

[kdrwila]

Hi,

I get this error when trying to submit form with a file:

"Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed"

From what I found unsetting file fields on EmailFactory level from form data passed to context ( files are preserved in attachements ) works fine

Stacktrace:

Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed

This is my current configuration, no configuration changes that have I made did anything, I'm using bolt 4.1.15 with symfony 5.2.5

[kdrwila]

Is there any way this can be fixed? The problem lies in serializing the whole form context in the mail factory when files should be omitted since they can't be serialized. I could make a PR which will fix the issue.

Actually, I did fix the issue myself but since MailFactory class is not injected I can't override it.

[doenietzomoeilijk]

The real fix is on the Symfony side, as far as I can see.

What fixed the error for me was only running the profiler for requests with exceptions, by setting framework.profiler.only_exceptions to true in config/packages/dev/web_profiler.yaml. Not an ideal solution, but at least it lets you get on.

There'd have to be a fix within the Symfony profiler itself for this to be fully solved, I'm afraid. Relevant issue here.
