PageView Pixel Code not activated

Hi,

We have this error message in some pages of our e-shop. It seems to be a bit random:

We detected event code but the pixel has not activated for this event, so no information was sent to Facebook. This could be due to an error in the code, but could also occur if the pixel fires on a dynamic event such as a button click.

You can check the error here https://ritarow.com/pants/ for example. It also happens in some product pages: https://ritarow.com/pants/tina/?attribute_pa_color=sand&attribute_pa_size=34

Is there anything we can do to avoid this issues?

Thanks in advance!
