verifyAccessToken giving crypto error

We have created a function in Realm Service of MongoDB atlas.

We are passing an okta generated access token to this function to get it verified.

We are using below code in the function

const claims = oktaJwtVfr.verifyAccessToken(’$oktaaccesstoken’,‘api://default’);

But we are getting below error when we call this function.

    "error": "'crypto' module: error verifying message",
    "error_code": "FunctionExecutionError",
    "link": ""

We have added ‘@okta/jwt-verifier’ dependency in the code.
Any suggestion please ?
