Your body tag or div ID is missing its corresponding header tag.
There are 3 places where your div ID should be found or configured for ad monetization to work properly. Audit the following:
Step 1: Ad unit code
Step 2: PubGuru header bidding configuration
Step 3: Source code
Off page:
On page:

Within <body> </body>
If it’s missing on page, verify if this unit should be part of your ad map.
- If not, remove it from the header bidding configuration.
- If yes, add the code per above guidelines
