When I try adding GTM container id (GTM-XXXXXX, GTM-six characters ) in discourse we are getting below error in browser console. Thought add https://tagmanager.google.com/, https://www.googletagmanager.com/, ‘unsafe-inline’ in content security policy script src settings.
But when I try to add GTM container id with GTM-XXXXXXX(Sever characters) , it’s working fine. I was able to get data in Analytics.
What is the solution for this issue ?
