[Data Integration] Explicit Period Mappings for file imports broken?
Hi everyone - I am experiencing an extremely concerning issue (submitting a severity 1 SR shortly as well), where our Data Integrations that use explicit Period mappings for a file-based import simply no longer work. The log claims that the period is invalid [ERROR_INVALID_PERIOD]. I've performed the following to no avail:
1) Confirmed that the Map Dimensions definition is correct and using the proper column from the file
2) Confirmed that the Period mappings are correct and match the values being imported
3) Restored production to test and retested (this integration worked prior to the Jan-22 update)
4) Delete all Period mappings and re-imported them
