Invalid endpoint message when using Node-Red-contribut-opcua

Hi All,
Trying to use Node-red-contribut-opcua, but I get the invalid endpoint message. both my Twincat and UAExpert connect no problem and also tried the palette opcua/for-node-red and that seems to work fine, so I'm at a bit of a loss, why it doesn't work.
On Debug I get this message about certification:

Blockquote

Error: Certificate file must exist :C:\Users\desousa\AppData\Roaming\node-opcua-default-nodejs\Config\PKI\own\certs\client_certificate.pem

Blockquote

I selected certification none, so I'm not sure why I get this.
Any info would be appreciated.

THank you.
Kind Regards
Luis

Best place to start would be read existing issues and raise a new one if needed:
