Aggregation endpoint error message is 'missing jzb'

If your Pendo subscription is in the EU instance (app.eu.pendo.io is where you login), please use this as the aggregation endpoint instead:  https://app.eu.pendo.io/api/v1/aggregation

If you try to use the US aggregation endpoint:  https://app.pendo.io/api/v1/aggregation, you will get the error 'missing jzb'.
