Nodejs app - node 10.15 complaining about JSON and global$1.fetch about pnp-auth

Cool, glad it works. If you know the exact steps taken, please post here, will be useful for others.

• new server uninstalled node 10.15 - re-installed node 8.15
• copy pasted the working project to the new server
• no changes what-so-ever
• run : same error !

AFAIK the only difference now is IISNode installed on the new server

So is IISNode intervening ? (the project is not linked - by me - in any way to IISNode)

If anybody has any pointers ... I'm taking all help I can get :)

thanks

It might be because of IISNode. As in my scenarios 8/10 no matter work.
Unfortunately, I have no experience with IISNode so without taking a look into this have no idea so far.

Out of interest, can you try pnp-auth's predecessors sp-pnp-node or node-pnp-js. Will it fail the same in your environment?

using node-pnp-js : samer error

(node:8256) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected token < in JSON at position 1
warning.js:18
at JSON.parse ()
at c:\Services\nodetest2\node_modules\sp-pnp-js\lib\odata\core.js:24:89

This is all the code there is

import * as pnp from 'sp-pnp-js';
import NodeFetchClient from 'node-pnp-js';

var credentials = {
    "siteUrl": "https://xxxxxxxxxxxxxxxxx",
    "strategy": "AdfsUserCredentials",
    "username": "xxxxx@xxxxxx",
    "password": "xxxxxx",
    "relyingParty": "xxxxxxx",
    "adfsUrl": "https://xxxxxxxx",
    "adfsCookie": "FedAuth"
  }
 
pnp.setup({
    sp: {
        fetchClientFactory: () => {
            return new NodeFetchClient(credentials);
        }
    }
});

new pnp.Web(credentials.siteUrl).get()
    .then(data => {
        console.log(`Your web title: ${data.Title}`);
    })

To get rid of "Unexpected token < in JSON at position 1" you should additionally set headers: { "Accept": "application/json; odata=verbose" }.

Have you tried that?

[dannyfoncke]

I've pestered the server admins and they have come with the announcements 'changed something in the host file to avoid wap' ...

Now it works. (all solutions)

Thank you very much for your time, really appreciated.

Maybe worth remembering when others come up with this error ?
