Your authenication token was incorrect for in-person signing ceremony via REST

I always get this error while trying to retrieve session id for the in-person signing ceremony using Iframe. Steps to reproduce using the below json payload I am able to create a successful package for the https://sandbox.esignlive.com/api/packages/tMs3tH1EWD3uKKQCgaLbjG64f-A=/clone The response contains a valid package id which I verified using the my eSign sandbox login

Using the package Id, I tried to create session token for the signerId "8eea7d5b-6a9f-42cb-979b-34eae00e04c1" which is there in the create package json payload. The URL used for obtaining session token is https://sandbox.esignlive.com/api/signerAuthenticationTokens The response succeeded with session token value which is given to the IFrame src value. https://sandbox.e-signlive.com/access?sessionToken=session token value I always get the Your authentication token was incorrect error I checked the browser developer tool console and found a CORS warning. I have attached the images for reference.
