The community member had an issue with the "is" function not working, but it started working later. The comments suggest that the issue may have been related to the UTM parameters passed to the Typebot's URL. Community members recommend creating a variable with the same name as the UTM parameters, such as utm_source, and using that variable in the Typebot. They also mention that the community member may need to use the self-hosted version of Typebot to avoid these errors. One community member provides a link to the Typebot documentation on forwarding UTM parameters.
