REST API Playground gives only 412 "Precondition failed"

[bomas13]

Using the build-in playground ends for me in any case with a response like:

{
  "error": "Not allowed"
}

and HTTP status code 412 "Precondition failed".

Even for the Lokalize endpoint which is currently usable even w/o any token it's exactly like that.

However, using the generated curl command works just like a charm. Unfortunately, there is no verbose output for debugging - what can I do about this?

Hi!

Did you set a token?

Or set a default public user role?

[bomas13]

No I did not set a role for unautherized request, because I don't want to allow such requests.
Yes I did set a token for my request. It's automatically set using the button next to a API key. And as I said: the generated curl command works like a charm and it's also containing the token.

Can't verify the issue. Do you get any errors in the network console?
