Build broken for test harness: recat dependencies unresolvable

[romeokienzler]

Followed the documentation to build the test harness but on npm install in /home/ubuntu/canvas/canvas_modules/harness I get:

npm ERR! code ERESOLVE

When bumping react from 16.13.1 to 17.0.0-rc.2 in package.json, I get:

So I'd say carbon is pinning react to <= v16, correct?

@romeokienzler What is the node version? These errors are usually seen in node 16.x.
Elyra-canvas uses node 14.x

[romeokienzler]

@nmgokhale 18.7.0 ;) thanks a lot! Will send an update tomorrow

I can confirm, this is broken on nodejs 16.. backing off to v14 seems to repair things.. any idea on a timeline for support ?

[nmgokhale]

npm install works fine for me on node version 14.20.0.

I will open an issue to upgrade to node 16.x. Until then, temporary workaround is running - npm install --legacy-peer-deps.

Thanks a lot @nmgokhale, downgrading to Node v14.x works fine for me
