  beforeAll(()=> {
        let form = frisby.formData();

        form.append('client_id', '1f3g3eff-acc2-4sdsd4');
        form.append('grant_type', 'password');
        form.append('username','test@example.com');
        form.append('password', 'test');
        form.append('client_secret', 'secret');
        form.append('redirect_uri', 'https://example.com/signin-callback');

        return frisby
            .setup({
                request: {
                    headers: {
                        'Content-Type': 'application/x-www-form-urlencoded',
                    }
                }
            })
            .post('https://example/token', {
                    body : form 
            })
            .expect('status', 200)

    beforeAll(()=> {
        return frisby
            .setup({
                request: {
                    // redirect: 'manual',
                    headers: {
                        'Content-Type': 'application/x-www-form-urlencoded',
                    }
                }
            })
            .post('https://example.com/token', {
                request:{
                    headers: {
                        'Content-Type': 'application/x-www-form-urlencoded',
                    },
                    body : 
                        qs.stringify ({
                    'client_id': '1f3g3eff-ac',
                    'grant_type': 'password',
                     'username': D.email('myAccount'),
                     'password': D.password('myAccount'),
                     'client_secret': 'secret',
                     'redirect_uri': 'https://example.com/signin-callback'
                         })
                }

            })
            .expect('status', 200)

application/x-www-form-urlencoded sample is the following.

return frisby.post('https://example.com/token', {
  body: qs.stringify({
    'client_id': '1f3g3eff-ac',
    'grant_type': 'password',
    'username': D.email('myAccount'),
    'password': D.password('myAccount'),
    'client_secret': 'secret',
    'redirect_uri': 'https://example.com/signin-callback'
  }),
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
  }
})
  .expect('status', 200);

i got it works like code below

  beforeAll(()=> {

        const myHeaders = new Headers();
        myHeaders.append("Content-Type", "application/x-www-form-urlencoded");

        const urlencoded = new URLSearchParams();
        urlencoded.append('client_id', 'sdsdsdf-b3d5-1c434ae452bb');
        urlencoded.append('grant_type', 'password');
        urlencoded.append("username", "acc@email.com");
        urlencoded.append("password", "test");
        urlencoded.append('client_secret', 'any');

        const requestOptions = {
            method: 'POST',
            headers: myHeaders,
            body: urlencoded,
            redirect: 'follow'
        };

        return frisby
            .fetch("https://example/default/token", requestOptions)
            .expect('status', 200)

Glad to see you got this working. 👍

After all, is it parameters value problem ?

The following values are different.

• client_id
• username
• password
• client_secret
• redirect_uri

'client_secret': 'secret',

urlencoded.append('client_secret', 'any');

As mentioned above, you were changing the value of parameters. I thought this is the cause.

Both do URL encoding, so I don't understand why URLSearchParams solves this issue.

However, it is nice to solve this !!

actually you were right, your way is working as well

i just noticed the difference, i wrapped headers and body inside request maybe this was the issue
