Need help with Dune config for publishing a package to Opam

I’m trying to publish a package to opam by following https://opam.ocaml.org/doc/Packaging.html#Publishing

But when I do opam install ., I get:

[ERROR] The compilation of jwt failed at "/Users/Sebastian/.opam/opam-init/hooks/sandbox.sh build dune alcotest".

#=== ERROR while compiling jwt.1.0.0 ==========================================#

My opam config is here https://github.com/sporto/ocaml-jwt/blob/master/jwt.opam
and dune https://github.com/sporto/ocaml-jwt/blob/master/dune

I don’t know how to config this correctly for publishing, any help or example that uses dune would be great. Thanks

I think I got this right now, Still will appreciate if you can tell me if my opam config is correct https://github.com/sporto/ocaml-jwt/blob/master/jwt.opam. Is the with-test correct here?

Yes, this is correct (for opam2) but you’re missing the build and run-test stanzas (like this one, so that’s probably why OPAM doesn’t really know what to do with your package.
