Root Cause

• Improper character encoding used: The request did not use the correct encoding standard (e.g., UTF-8), leading to parsing errors.

• Unsupported special characters: The request body contains unsupported or invalid special characters that the gateway cannot process.

• Incorrect content-type header: The request did not specify the correct Content-Type header (e.g., application/json or application/x-www-form-urlencoded).

Troubleshooting and Solutions

• Verify that the request uses the correct character encoding standard, typically UTF-8.

• Ensure that the request payload does not contain unsupported special characters or invalid symbols.

• Confirm that the Content-Type header is correctly set based on the type of request payload being sent.
