Error when generating Typescript definitions

[bjtrounson]

Been having a little issue with generating Typescript definitions for the past few days, wondering if anyone would be able to give me some pointers or if I'm approaching this correctly.

I've been working on restructuring Ferrostar react-native project in a more mono-repo like structure so we can have our uniffi-binding, core, view logic all be in separate projects so someone can import them all independently of each other. This would also align better with how are other platform's are structured.

Currently I haven't been able to get the Typescript definitions to build as I get the error below. I have been wondering if this issue is related to #196 but it seems to be a different output.

Sorry to get back to you a week later!

I am not the Typescript expert on the project, however: I believe that when we've found this issue in the past it's been fixed by changing tsconfig.json, and that the long term fix is #198 . Nominate @zzorba or @hassankhan for better help.

I don't exactly what remember that I did here, I think I just told tsconfig to 'exclude' my generated source code.

There's a discussion of a possible workaround for this, but I'm failing to understand the difference they are calling out here: microsoft/TypeScript#61249
