Cannot access to UI due to influxdb misconfiguration

General

Hello,
I had to reinstall influxdb but unfortunately I forgot to update node-red-contrib-influxdb nodes so now I am not able to access to nodered UI.
Looking at logs it tells:

at new RequestError (/data/node_modules/influx/lib/src/pool.js:52:28)
at IncomingMessage.<anonymous> (/data/node_modules/influx/lib/src/pool.js:62:53)

12 Feb 14:56:02 - [error] [influxdb out:3de57654.f35602] Error: A 401 Unauthorized error occurred: {"error":"authorization failed"}

So I tried to remove node-red-contrib-influxdb but now the logs tells:

and in the same way the UI is unaccessible:

Is there any way to fix this?

Missing nodes should not stop the ui from running. Have you tried refreshing the browser?

3

You should be able to reinstall them from the command line
cd .node-red
npm install

I was using firefox under Windows and I got the blank UI.
Then I am using safari and all looks right... I had to better investigate the issue

Yes I did it!
