Axios PUT Request: XSRF-Check Failed

[wolfbiker_1]

Hello everybody,

i want to modify Jira Ticket descriptions from my ReactJS Application. Therefore I figured out how to connect to Jira with the RestAPI - no problem so far, I used the tool Insomnia to check the database endpoint. Everything went fine. The description gets updated, the Server response is 200.

When doing so from my React App i use the following code:

 axios.put(url, {
   method: 'put', 
   headers: { 
       'Authorization': `Basic ${token}`, 
       'X-Atlassian-Token': 'no-check',
       'content-type': 'application/json'
   }, 
   data: { 
       "fields": { 
            "description": "foo bar \r\n\r\n\r\n"
         }
   } 
})

When doing so from my React APP, everything i get is the following:

Error 403 - "XSRF check failed"

So I suspect that something with the header is wrong, because this error is usually a sign, that the AtlassianToken isn't set.

Can somebody see what's going on here? Obviously, the header information doesn't reach the server.
Here is the Server Response:

Thans in advance!
