Bad request when creating custom fields

Newbie here! I’m trying to create a custom field to use in escalation policies.
When creating the custom field, I keep getting a ‘Bad request’ error: name: can only contain a-z 0-9 and ....

However, the Field Name nor the Field Options contain anything but letters (no white space either). Anyone else running into this problem / know a solution?

Thanks in advance!

Hello @christien.kerbert!

You are probably using an upper case letter in the “name”. a-z means lower case letters.

Hope this helps!
