Thanks in advance for your feedback!

Can you run Node-RED with the safe parameter to stop the nodes loading? If that works then most likely that node is causing an issue.

While you are at it, make a backup and upgrade Node-RED to the latest v1.3.2 if you can.

When you try to uninstall via the command line are you going into the .node-red folder first? If so what copy/paste here the command you are using and what it says.

I launched Node-RED with the safe parameter but it keeps giving me the same error.
I updated node-RED to v1.3.2 and the error has changed.

I have backed up the flows, should I do a clean installation of node-RED?
Thanks

No. This error is related to a node you have installed.

You mentioned you had installed one and was unable to remove it. As @Colin has asked, can you show us the output of trying to remove it so we can see how you are doing it?

It should be a case of running npm remove node-red-contrib-ecb-euro-exchange-rates from within the .node-red directory.

C:\Users\lino->cd .node-red

C:\Users\lino-\.node-red>npm remove node-red-contrib-ecb-euro-exchange-rates
removed 52 packages and audited 168 packages in 1.145s

12 packages are looking for funding
  run `npm fund` for details

found 2 low severity vulnerabilities
  run `npm audit fix` to fix them, or `npm audit` for details

I removed the node with the command you indicated in the path you indicated, now it works!

Thank you very much!
