Node.js example suggests JSON.stringify which will modify UTF-8 characters

[mrcljx]

Environment

Node.js 18

Steps to Reproduce

1. Implemented integration following TS example.

   function getSignatureBody(req: Request): string {
    const stringifiedBody = JSON.stringify(req.body);
    // HACK: This is necessary since express.json() converts the empty request body to {}
    return stringifiedBody === '{}' ? '' : stringifiedBody;
   }
   

2. User with special character in their name couldn't use "Create Issue" integration (401)
3. Reason was a signature mismatch.
4. Raw JSON payload ended in

   {/* ... */,"actor":{"type":"user","id":1,"name":"John Do\\u00e9"}}

Expected Result

Signature match.

Actual Result

Signature did not match.

Analysis

Calling JSON.stringify replaces \u00e9 with é.
