hello all, i am building an app with remix frontend and express at backend for every request i am sending jwt from the frontend. But the issue is it doesn’t get verified using the shopify api secret key always getting Invalid token signature error

Hi, this is an incredibly vague post.

I’d suggest sharing any errors, logs, and any code you’re using. Share any troubleshooting steps you’ve also followed.

its an older app so should i be using the app secret direclty or with something else .when i test it with a app locally it do work but once i update and deploy with the older app but with same configuration i am getting error.no other issues only signature mismatch
