(Docker) error: Unexpected argument '/usr/bin/swift-build'

[iandundas]

I had swift package --disable-sandbox vercel deploy --prod working (successfully deploying to Vercel) last week, but today I went to run the same deploy command and got the error below.

I think Docker was updated in the interim, but otherwise I can't think of what changed.

I tried (rather cluelessly):

• restarting Docker
• deleting the docker container (so subsequent command re-downloaded it)
• deleting the ./build folder

$ swift package --disable-sandbox vercel deploy --prod
