Crash due to mismatched Lair Keystore version

[pospi]

I'm first logging this issue at the leafmost point in the dependency chain because it's probably a build system thing, but it could also be due to upstream complications in the Holochain Launcher, Neighbourhoods Launcher, or Sensemaker Lite.

Ever since getting the Holochain Launcher setup for local development outside of Nix I have had this problem.

Holochain throws a misleading error but the logfiles show that:

Other({"error":"Invalid lair server version, this client requires '0.2.3', but got '0.2.4'."})

CC @weswalla @nick-stebbings @zippy @guillemcordoba @matthme

For completeness, the Sensemaker DNA appears to be built with hdk@0.2.0 and hdk@0.1.0 whilst hREA DNAs are built with hdk@0.2.1 and hdk@0.1.1. This has never been an issue before. My nix env has holochain_cli 0.1.3, holochain 0.1.3.

Terminal output as follows:

$ AGENTS=1 UI_PORT=8888 npm run launch:happ

> launch:happ
> RUST_LOG=warn WASM_LOG=debug echo "pass" | hc launch --piped -n $AGENTS ./workdir/sensemaker-enabled/provider-sensemaker.happ --ui-port $UI_PORT network mdns

@matthme actually this turns out to be a problem with mismatched Lair Keystore versions after setting up the Holochain Launcher for local development. Original issue description updated.

Can you let me know how to reverse whatever setup step I ran which is now causing the mismatched version error? I didn't have my CLI logs as well tended to as I had imagined :/

[pospi]

Actually, thinking about it more and wonder whether the issue is that the Holochain Launcher I've built off the develop-0.1 branch is actually setup to reference older dependencies (Lair 0.2.3) than the current Nix environment for Holochain 0.1.3 (Lair 0.2.4) and therefore does not work within this environment?

[matthme]

If your environment is expecting lair 0.2.4 I assume that it is also at holochain version 0.1.5 as the lair version had a bump between holochain 0.1.3 and holochain 0.1.5. The develop-0.1 branch of the Launcher is at Holochain 0.1.3, i.e. requires lair 0.2.3

[pospi]

I will need to upgrade to a later Holochain Nix env then I think. @weswalla @nick-stebbings @guillemcordoba do you forsee any issues running the Neighbourhoods Applet binaries in a Holochain 0.1.5 environment?

[pospi]

Resolved in upgrading to Holochain 0.1.5
