Hi SachinNandanwar  - I'm happy to help here.  The reason you are receiving the error message regarding a bearer token is because, since all OneLake SAS are user-delegated, the SAS is authenticated very similarly to how a bearer token would, hence the similar error. 

From reviewing the samples above, your issue might be with the signedPermissions ('sp') field - it looks like you're only granting the SAS Write and List permissions, which means the SAS won't have permissions to Read, hence the authorization error.  Could you try adjusting the signedPermissions and trying again?

    Hi Mabasile_MSFT 

    I added the read permission but unfortunately it didnt make any difference.
