I tryng to get a token with a JS Client. so I configu my client just like the image, and this is my code (Axios) to try to get the token: this.axios.post(' http://localhost:9090/auth/realms/Lumera/protocol/openid-connect/token';, { username: this.email, password: this.senha, grant_type: 'password', client_id: 'central-api' }, { headers: { 'Content-Type': 'application/x-www-form-urlencoded', }, }, ).then((response) => { console.log('ok'); }, ).catch((error) => { console.log('erro'); }); but I got the error: Failed to load http://localhost:9090/auth/realms/Lumera/protocol/openid-connect/token: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 400.
