Deploy NX Angular Monorepo App: Failed to compute cache key, no such file or directory

Questions / Help Build debugging

Hello,

I’m currently trying to deploy an NX Angular Monorepo App but am getting an error

Please note that I’ve replaced the actual app name with [app] so that it is clear. Also because this is a monorepo, when we run the build command, we then try to reference a directory /dist/apps/[app]. Serve small with Fly.io and GoStatic · Fly has been reference.

 => CACHED [stage-1 2/3] RUN npx nx build geoaudit --prod                                                                                                                                                         0.0s
