Describe the issue

We're running dbt Cloud Versionless in our dev and prod environments, and yesterday we have started getting the metricflow_time_spine related error that does not allow us to run any run/compile/build commands.

We have fivetran ad_reporting package that seems to have a semantic model and generates metricflow_time_spine inside.

We don’t have a spine model in our own project and don’t specify it.

Relevant error log or model output

22:13:54 Encountered an error:
Object of type date is not JSON serializable

Expected behavior

The models should continue building.
