When migrating flows stored in a local directory that contains subflows the import will fail. Flat flows import as expected.
There is a message that says "Migration completed with errors, The following flows were not able to be migrated". The flow referenced will be a subflow contained inside the flow we are trying to import which suggests an issue when these are being unpacked.
