Uploading an invalid JSON gives error 500

I had an error 500 when following along the vue3 i18n tutorial while running this command:

lokalise2 file upload --lang-iso en --file "./src/i18n/locales/en.json" --project-id <my project id> --token <my api token>

I got the following:

Uploading ./src/i18n/locales/en.json...
Error: API request error 500 Something went wrong. Please contact support if the issue repeats.

API request error 500 Something went wrong. Please contact support if the issue repeats.

I thought that I messed up the API token or the project ID, I then tried to upload the file through the web dashboard and got an error that the JSON was invalid. I fixed it and tried to upload via the CLI again and it worked. Would be nice to have the same error in the CLI instead of a generic 500.
