After successfully setting up our Facebook pixel using Google Tag Manager, I encountered an error message while using the "Google Pixel Helper" Chrome plugin to check the pixel.
Even though I copied and pasted the code directly from Facebook, the error persists after double-checking and re-pasting it. Please refer to the attached image for the exact error message.
You can view the implementation [here](https://valg.redbarnet.dk).
If anyone has any suggestions on how to proceed from here, please let me know!
