Rejected go_darwin_arm64 mismatching values: x86_64

I'm trying to get a Bazel build working on my MacBook Pro M1 on Monterey, and I'm having a difficult time. When I try to build a docker image, I get go toolchain errors (with --toolchain_resolution_debug='go') that look like this:

INFO: ToolchainResolution:     Type @io_bazel_rules_go//go:toolchain: target platform @local_config_platform//:host: Rejected toolchain @go-auto//:go_darwin_amd64-impl; mismatching values: x86_64
INFO: ToolchainResolution:     Type @io_bazel_rules_go//go:toolchain: target platform @local_config_platform//:host: Rejected toolchain @go-auto//:go_darwin_arm-impl; mismatching values: arm
INFO: ToolchainResolution:     Type @io_bazel_rules_go//go:toolchain: execution platform @local_config_platform//:host: Rejected toolchain @go-auto//:go_darwin_arm64-impl; mismatching values: x86_64

Why does it say it rejects an arm64 implementation because it's not x86_64? It seems like there's something broken here.

For reference, here's bazel version:

Bazelisk version: development
Build label: 5.2.0
Build target: bazel-out/darwin_arm64-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar

And some relevant bits from my WORKSPACE:

If you'd like to build for linux x86_64 on arm, --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64 works for me. The x86 container will run in emulation on the arm machine.

You could probably target an arm linux container with toolchain:linux_arm64
