Hi Y'all! I'm working on a Spin SDK for Go, and I'm trying to troubleshoot a WIT-related error:

# Run inside go/examples/spin-basic
$ spin up
Logging component stdio to ".spin/logs/"
Error: failed to resolve dependencies for component "spin-basic"

Caused by:
   0: an error occurred when preparing dependencies
   1: failed to decode world from module
   2: failed to reduce input adapter module to its minimal size
   3: adapter module does not have export `wasi:otel/tracing@0.2.0-draft:outer-span-context`

I think I'm properly generating the bindings (intellisense works):

# Commands in go/Makefile
$ wkg wit fetch -d ../wit
$ wkg wit build -d ../wit
$ go tool wit-bindgen-go generate --world imports --out internal ./wasi:otel@0.2.0-draft.wasm

I'm certain it's not an issue with the WIT files not exporting outer-span-context, which leads me to guess that I'm not properly pulling the dependencies together. Any thoughts?

For context this work is related to #wasi-observe

Are you using the special version of Spin that implements wasi-otel?

Yes

@Andrew Steurer I think you'd get more responses in the cncf Slack's spin channel, as this Zulip is very much focused on Bytecode Alliance-hosted projects
