Can't have forward slash (/) under Settings → Notifications → Mention and keywords

[SethFalco]

Steps to reproduce

1. Navigate to Settings → Notifications → Mention and keywords
2. In the Keyword field, input any text containing a forward slash. (/)
3. Select Add

What happened?

A modal appears with the following text.

Error saving notification preferences

An error occurred whilst saving your notification preferences.

And the content of the Notifications setting changes to.

Notifications

There was an error loading your notification settings.

---

I can just flip to another page, then return to Notifications settings to access the page again. (The keyword does not get added.)

What did you expect?

I would expect the keyword to get added as it would for any other keyword.

If for whatever reason, not that I can think of one, a / cannot be used in a keyword for a logical/technical reason, then I would expect the field to have validation explicitly warning the user. (Or handle it gracefully one way or another.)

It seems that / is rejected by backend, we need to add some front-end validation for that too.

[Palid]

It also shouldn't just show There was an error loading your notification settings after showing modal that something has failed.

[SethFalco]

Sorry @Palid, just need to verify.
Did you close this issue in intentionally in favor of 18778 or did you perhaps target the wrong issue?

It doesn't appear to be related?

[SimonBrandner]

Yeah, seems unrelated, @Palid, I think you closed the wrong issue?

[Palid]

@SimonBrandner yeah, seems like I got entangled within open tabs. I'll fix it tomorrow, thanks for catching!

[Palid]

Okay, fixed incorrectly referenced issues, thanks for figuring this out @SimonBrandner !

I'm not completely familiar with the workflow of the project, but could it be the project needs to be changed back manually too?

Yes, you're right. Fixed that too.
