Error "Snowplow: Function failed" from ping.js in console

Question

Ever since we implemented Google Tag Manager, we're seeing a console error on our website from ping.js: "​Snowplow: Function failed"

 TypeError: Cannot read properties of undefined (reading 'call')
    at Function.<anonymous> (ping.js:7:7795)
    at I (gtm.js?id=GTM-TL3VCNL:34:661)

error @ ping.js:7

How do we fix this?

Answer 1

If you don't know where it is or who installed it.

You can export the Google Tag Manager container.

It's a JSON file then open it with your editor and find the keyword.

You should see it is wrapped in an object where contains tagId or name.

Then you can use the name to check on the GTM UI. Try to pause it or asking the relevant people who knows about this.
