Can't upload the custom campaign

[Trailblazer]

Hi all, I am fairly new to the site and have never posted a campaign before. There is this custom campaign I have been working on but when I completed everything needed, including attachments, ater clicking the post bundle button, always the same error message comes up:

Oops! We ran into some problems.
A server error occurred. Please try again later.

I've tried posting without adding used assets still the same results.
Also tried with screenshots from a different site and without screenshots, still the same, so I'm guessing there is maybe some error in the draft

This is what it looks like. I would be very grateful if somebody can take a look into it and help me.

That link doesn't show other people your submission. Better to add a screenshot to paste (under "utility") and post that link here.

Ah I see that. Well, i uploaded it currently under Maps Development since I haven't encountered that issue. Also aything related to the campaign will be discussed there. Thank you for the very fast reply still
