Hello, @jhTuppeny - Thanks for reaching out. It looks like the .csv
type is among the allowed types and I'm able to reproduce the same issue you're hitting with the Azure Communications Services connector. I suspect it's so because the connector is in the Preview stage but I'll clarify & confirm with the owning team and share my findings here.
UPDATE: I believe the Connector's page is meant to list these types under its "Known Issues and limitations" section. I've requested confirmation internally but it's likely a supportability issue that'll be resolved when the connector goes GA.
