RE: Error deploying ReactJS portlet
Liferay version: DXP 7.1 SP10
JS portlet extender version 1.1.0
Hi there - I'm testing out the creation of a React-based portlet and while it initially worked as advertised, I'm starting to see errors in the log so the portlet no longer works.
This is happening for both my custom portlet and newly-generated React portlets via the Yeoman generator. In addition, I see this error in the browser console:
Can anyone assist? Since I just started this process and I generated the portlet via Yeoman, I'm using the latest versions of the bundler and so forth.

Hi Sandra:
First of all, can you follow this -> https://github.com/liferay/liferay-js-toolkit/wiki/How-to-troubleshoot-your-setups so that we can get more useful information? Using production settings makes it very hard to find out anything.
Also, do you know what changed between the moment it worked and after? Did you add any specific dependency for example?
Thx.

Hi Ivan - here's what I get in the console after enabling debugging from your link:
I also see:
Liferay AMD Loader: Unhandled failure: Error: The following problems where detected while resolving modules:
Package create-event-reactjs$react which is a dependency of create-event-reactjs@1.0.0 is not deployed in the server

at Loader._getResolutionError (loader.js:331)
at loader.js:218 while resolving modules: ["create-event-reactjs@1.0.0/index"]I also see:

Hi Sandra, Please follow the steps https://portal.liferay.dev/docs/7-2/appdev/-/knowledge_base/a/developing-a-react-application if not followed. I tried today and working as expected.
Sandra is working on 7.1 ... you just pointed her to the 7.2 documentation. Did you use the 7.2 docs on a 7.2 install? or are you saying that those steps are working on a 7.1 install?
