Rojo sourcemap.json not found

[UW4Z (Max)]

I followed every step in this tutorial (https://www.youtube.com/watch?v=IJDg6tRJmHo) until the step where you have to run wally-package-types -s sourcemap.json Packages/

Before running that command I ran: rojo sourcemap default.project.json --output sourcemap.json to create a sourcemap.json file.

After running that command I ran: wally-package-types -s sourcemap.json Packages/
and got this error: error: Failed to read packages folder: The system cannot find the path specified. (os error 3)

Any ideas why wally-package-types -s sourcemap.json Packages/ would lead to this error if I already have a sourcemap.json file?

It’s because you don’t have any wally packages installed so you don’t need to do this step.
