dbt jobs failing with 'resource names cannot contain spaces' error for some customers on US MT, MC1 and MC3

We have observed multiple job failures from a subset of customers beginning at approximately 8:00 PM UTC on 22 May. These failures are returning the error message: "resource names cannot contain spaces" This behavior is the result of a previously communicated change that enforces stricter validation on resource names (eg, models, sources). The change has now been applied, resulting in the failures. Only customers whose projects with resource names containing spaces are affected. The change was rolled back at 3:10 AM UTC on 23 May to prevent further disruption and allow impacted customers time to adjust their configurations. We are continuing to monitor the situation to ensure stability.
