I am getting an error pushing up an update. Error:
Copy code
docker:index:Image (fantasy-rust-api):
    error: error reading build output: process "/bin/sh -c cargo build --release" did not complete successfully: exit code: 101
But when I run
cargo build --release
it succeeds
Copy code
cargo build --release
   Compiling fantasy-api v0.1.0 (/Users/adamambrosius/mwg/fantasy-api)
    Finished release [optimized] target(s) in 19.61s
How can I get this to successfully read the build output?
It was my error. Sorry about that. Found it by running a docker build which showed I was looking for a file with a uppercase W instead of lowercase w.
