Hello @LevisThors,

It can be a lots of things, can you share your repo, I'll take a quick look.

[LevisThors]

@juliens, here's my repo - https://github.com/LevisThors/traefik-auth-plugin/blob/main/plugin.go
I register it in docker-compose like this:
command: ... - "--experimental.localPlugins.authplugin.moduleName=github.com/LevisThors/traefik-auth-plugin" ...

Oky, and how do you compile your plugin to wasm?

Because wasmexport is not supported officially in go, so you need to compile with tinygo OR build with the master branch of go ( and to use a specific version of the http-wasm-guest based on this http-wasm/http-wasm-guest-tinygo#34 )

[LevisThors]

I use the commands from demo makefile - https://github.com/traefik/plugindemowasm-http-call/blob/main/Makefile

[juliens]

Oky so you need to change the http-wasm-guest-tinygo version in go.mod like in the demo go.mod

It worked, thank you so much!

Added this line to my go.mod
replace github.com/http-wasm/http-wasm-guest-tinygo => github.com/traefik/http-wasm-guest-tinygo v0.0.0-20240913140402-af96219ffea5

Also, I came across another issue when sending request, is it connected with this one?
wasm error: out of bounds memory access wasm stack trace: .handle_request() i64

[juliens]

Did you use the last Traefik version?

[LevisThors]

I was using v3.1.2, updated to v3.1.4 and now it works as expected.
@juliens thank you!
