QSH Verification, I have tried to verify qsh string but i get a "abc" qsh instead of the "def" qsh from the JWT token

I have used this video to properly understand how JWT QSH is created from a SHA hashed conical requesthttps://www.youtube.com/watch?v=5EpEMKPbUjU

I also have gone through, this site Understanding JWT. https://developer.atlassian.com/cloud/jira/platform/understanding-jwt-for-connect-apps/.I have replicated everything done there, and still confused. I have never been able to reproduce the qsh.

 if (verifiedClaims.qsh) {            const { baseUrl } = payload;            const url = JWTHelper.decodeUrlToMatchJWTQueryStringHash(baseUrl);            logger.debug(`url[${url}]`);            const req = jwt.fromMethodAndUrl("GET", url);            logger.debug(`req[${JSON.stringify(req)}]`);            let expectedHash = jwt.createQueryStringHash(req);            logger.debug(`expectedHash[${expectedHash}]`);            let signatureHashVerified = verifiedClaims.qsh === expectedHash;            logger.json("signatureHashVerified", { qsh: verifiedClaims.qsh, expectedHash, signatureHashVerified });            if (!signatureHashVerified) {                // If signatureVerified is false, then check the url if its a PUT/POST                expectedHash = jwt.createQueryStringHash(req, url);                signatureHashVerified = verifiedClaims.qsh === expectedHash;                logger.json("signatureHashVerified", { qsh: verifiedClaims.qsh, expectedHash, signatureHashVerified });                if (verifiedClaims.qsh !== expectedHash && verifiedClaims.qsh  !== "context-qsh") {                    const canonicalRequest = jwt.createCanonicalRequest(req, true, url);                    logger.error('Auth failure: Query hash mismatch: Received: "'+ verifiedClaims.qsh +'" but calculated "'+ expectedHash +'". '+'Canonical query was: "'+ canonicalRequest);                    throw new Error("Authentication failed: query hash does not match.");                }            }        }

The code above is from the Link, understanding jwt. I am using atlassian-jwt npm packagehttps://www.npmjs.com/package/atlassian-jwt.

Please where am I getting it all wrong, from my codes or from any perspective what can I do to fix the issue and verify qsh
