Summary

User encountered a KeyError during schema discovery for Facebook Marketing source with ‘mmm’ breakdown, indicating a discrepancy between the source setup and schema definition.


Question

Hi all!
I tried to set up a new Facebook Marketing source with “Custom Insights” and the “Breakdowns” set to mmm .
The source was saved successfully.
When setting up a connection, discovering the schema failed with error message: KeyError: 'mmm' .
After digging in the code, I found that Facebook Marketing Source setup page is using the facebook_business Python package, which contains mmm as valid breakdown.
However the “ads_insights_breakdowns.json” schema (which I guess is used when discovering the schema) doesn’t have mmm as a valid property.

  1. Is this the right place to make a change request to add mmm as a valid property?
  2. Is it by design that the source setup screen and the schema discovery code are using different sources of truth to identify valid breakdowns?
    Thanks! :pray:
