Unable to run Google Analytics sample code

[Wing Hang Khoo]

I was following two guides from the Google App Script Reference

guide 1: https://developers.google.com/apps-script/advanced/analytics?authuser=0

guide 2: https://developers.google.com/apps-script/advanced/analyticsdata?authuser=0

But I'm getting the error: GoogleJsonResponseException: API call to analytics.data.ga.get failed with error: User does not have sufficient permissions for this profile.

I have confirmed with my boss I am getting admin privileges. I have also checked on Google Analytics admin > property > property access management that I do have admin access.

I have two questions.

First one is, should I use the tracking ID or create a new property ID.

Second question is how am I able to get permission to run the codes.

I used tracking ID for the above codes, so UA-used_ID-1.

Thank you for the help.

Not too sure if I should be using the tracking ID or create a new property ID. The above error I got was using tracking ID. I have confirmed I have admin privileges, so not too sure why I am getting this error.
