Bazel/Golang: rule 'go_embed_data' doesn't contain declared provider 'GoArchive'

Question

I'm trying to create a Bazel rule for my project that just embeds a collection of files. The embed rule is as follows:

go_embed_data(
    name = "my_files_go",
    src = [
        "embedded/src1", "embedded/src2"
    ],
    package = "my_lib",
    var = "myFiles",
)

Which I then add in my go_library rule:

go_library(
    name = "library",
    srcs = [
        "library.go",
    ],
    importpath = "github.com/nickfelker/golang-app",
    deps = [
        ":my_files_go"
        "//otherLib",
    ],
)

However when I try to build this, I end up getting an obscure error that I cannot find elsewhere.

Error: <target //library:my_files_go> (rule 'go_embed_data') doesn't contain declared provider 'GoArchive'
ERROR: Analysis of target '//:binary' failed; build aborted: Analysis of target '//library:library' failed

How am I supposed to get around this error?

The rule created for go_embed_data does not go as a dependency to the go_library rule. Instead, it should be considered one of the srcs, as so:

go_embed_data(
    name = "my_files_go",
    src = [
        "embedded/src1", "embedded/src2"
    ],
    package = "my_lib",
    var = "myFiles",
)

go_library(
    name = "library",
    srcs = [
        ":my_files_go",
        "library.go",
    ],
    importpath = "github.com/nickfelker/golang-app",
    deps = [
        "//otherLib",
    ],
)
