This error means the
bes_timeout flag is likely set to a value that's not long enough for bazel to finish uploading all build artifacts.
We recommend using the following flag to increase this upload timeout:
These slow uploads should only happen once when artifacts are initially written to the cache, and shouldn't happen on subsequent builds.
If your build has finished but you're frequently sitting around waiting for build events to upload - you're likely in a network constrained environment trying to upload large build artifacts like docker images or large binaries.
For network constrained environments, we recommend running with the flag:
This will upload build, test, and profiling logs - but not the larger build artifacts that can take much longer to upload.
