I'm a bot. Here are possible related and/or duplicate issues (I may be wrong):

- https://github.com/dotnet/aspnetcore/issues/50252
Is it possible to provide the raw HTTP request that postman sends for both these cases? Per company policy, we're not allowed to run postman. And from the linked issues, it seems like postman might be sending the form in an "unusual" way that we aren't familiar with since "normal" file uploads work when we try them.
