Pnpjs: syntax error: Unexpected token < in JSON at position 0

[muraray]

Category : Question

I am using SharePoint 2013 On-Premise. I have written following code to get web title and description:

pnp.setup({
            headers: {
                "Accept": "application/json; odata=verbose",
            }
        });

pnp.sp.web.select("Title").get()
      .then(function (data) {
           if (data.d != undefined) {
               console.log(data.d);
            }
     });

But I am getting following error:

syntax error: Unexpected token < in JSON at position 0

Are we missing something here? we did gone through this issue and tried the solution never worked

Hi @muraray,

Yes, you're missing one thing actually. Please check the docs article.

TL;DR:

sp.setup({
  sp: { // < this is missed
    headers: {
      "Accept": "application/json; odata=verbose",
    }
  }
});

so you end up with default application/json; odata=minimalmetadata instead.

A difference here is that PnPjs in compare to PnP-JS-Core supports not only SP REST but Microsoft Graph API for example.

Thanks a ton for guiding me...

Yes, i found the way back after checking the document...

another question, Is there any other way we can get the parent site absoulte url without using the SPHostUrl and SPAppWebUrl querystings? (currently i'm so dependent on these querystrings)

All my data are present in parent site. I found from the documentation that we could use the config the baseUrl during the pnp setup properties but i don't want to hardcoding strings as baseUrl properties.

Any suggestions please.
