HTTP Post error in IOS

Ionic Native
1

Hi, I need help in resolving this issue. I’m facing issue when doing POST request to get the access token in IOS. Whereas it works fine in Android.

Code:
const bodyParams = {‘client_id’:clientId,‘client_secret’:secret,‘grant_type’:‘authorization_code’,‘code’:tokenOrCode};

const httpResponse = await this.http.post(accessTokenUrl, bodyParams, {“Content-Type”: “application/json”});

Error:
{“error”:“invalid_client”,“error_description”:“FBTOAU204E An invalid secret was provided for the client with identifier: ‘abc@abc.com’.”}

Note: The above code works without any issues in Android.
