This error occurs when the default consent state has not been defined or properly configured during the setup of the CookieYes CMP Tag in GTM. The issue can also occur if you used the Custom Script method to implement GCM but either missed adding the custom script or included a script with missing elements.

If you’ve implemented Google Consent Mode using the CookieYes CMP template:

  1. Update the CookieYes CMP tag. To do so,
    • In the Google Tag Manager workspace, click Templates in the left sidebar and locate the CookieYes CMP template. 
    • Click on the Update icon.update CookieYes CMP
  2. Ensure proper setup of default consent settings by following these steps:
    • From the Tag Manager workspace, select Tags from the left sidebar. Next, click on the CookieYes CMP tag and then click the edit icon.
    • Click Add Setting.
    • Select Enabled/Disabled from the drop down for each cookie category based on your requirements.
    • Set the Region by entering the region’s ISO-standardised (ISO 3166-2) codes for the specific regions you intend to Geo-target with your banner. If you prefer not to Geo-target your banner to specific regions around the globe, enter All in the Regions field. Refer to the ISO 3166-2 standard for the appropriate region codes.
    • Click Add.

    • Submit and Publish the changes to your google tag manager container.

    a. Open Tag Assistant debug console.
    b. In the Summary, select the Tags tab.
    c. Click a tag to check if it fired according to the consent settings.
  3. If you used Custom Script method to implement GCM, check the order of the script is as follows:
    i. Custom Consent Mode script
    ii. gtag / GTM script
    iii. CookieYes script
  4. Ensure you do not place other scripts above the Custom Consent Mode script.
