Steps to reproduce
- Go to Administration > Vocabularies
- Choose "nature"
- Add an entry with id = https://adress.com/ and label = blabla
- Observe the entry is correctly added
- Click on the Delete icon for the new entry
- Observe an error is displayed
- Click on the Edit icon for the new entry, change the label and submit the form
- Observe an error is displayed "Failed to fetch"
The error on Delete could be reproduced with a curl command
The problem seems to be related the forward slash in the entry id which is not encoded.
