What did you do?

I have a genrule like:

genrule(
    name = "foo",
    srcs = [],
    outs = ["foo.txt"],
    cmd = "touch foo.txt > $@",
    toolchains = [
        "@io_bazel_rules_go//go:toolchain",
    ],
)

What did you expect to see?

That this toolchain is successfully provided to the execution of the genrule.

What did you see instead?

'@io_bazel_rules_go//go:toolchain' does not have mandatory providers: 'TemplateVariableInfo'
