You are not sending a valid Event_name parameter for some of your even

I am facing this error. What should I do in the Google tag Manager to rectify this? Someone please guide me <3

the errors are literal

for first one you are sending old cookie values, so I would look into how you form the payload how they are being set in the first place etc.

for second error some of your events are not sending event name - again, to give you any advise need much more information on your setup than just an error text

What kind of information Sir. All of these were working fine until a few days back. Can you please guide me please

Unfortunately I don’t think it’s possible to sort this out without access to your tracking with an audit of the setup and how it works. I would recommend contacting a tracking specialist who can check this for you.

Also note that Meta interfaces have been glitching a lot lately. Try waiting a while, it may just be a false positive.
