I think we need to assign exact versions to jsonrpsee, not to break the build.

I plan to release a new version soon after https://github.com/paritytech/jsonrpsee/pull/243/files is merged which has breaking changes and future alpha releases might break it too.

Thanks @niklasad1, I will hold this back until new jsonrsee released. Let me know.

[niklasad1]

If we can get in #250 it should be good to go.

[ascjones]

Also need to get all tests passing in #253

Looks like #250 is the only thing blocking this yes?

[ascjones]

Yeah, I'll check it again and merge it if it looks good

[ascjones]

Ready to go I think, just needs a ✔️
