Hot to retrieve the Sparepoint Guid by given ItemId

Question

I am wondering whether there is way to retrieve the Guid (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) from an given ItemId (eg. ItemID=1969 as in query params in https://xyz.sharepoint.com/path/to/documents/image.jpg?ItemID=1969&ItemVersion=5.0) with pnpjs under nodejs. The docs do not describe how to do that but there might be a way to use a "back-door" to achieve this. I would like to do something similar like:

sp.web.
  .getById(1969)
  .get()
  .then((file) => {
     doSomethingWith(file.UniqueId); //UniqueId is supposed to be the guid (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
  })
...

Any suggestions are welcome. Cheers

Answer 1

You could use the below way to retrieve the file uniqur id

  sp.web
    .lists
    .getByTitle("Documents")
    .items
    .getById(80)
    .file
    .get()
    .then((file)=>{
      console.log(file.UniqueId);
    })

I think you should use "GUID" instead of "UniqueId" see this link and find this part of the documentation.

Retrieve specific list item The following example shows how to retrieve a specific list item.

HTTP GET

https://{site_url}/_api/web/lists/GetByTitle('Test')/items({item_id})
Authorization: "Bearer " + accessToken
Accept: "application/json;odata=verbose"

The following XML shows an example of the list item properties that are returned when you request the XML content type.

XML

<content type="application/xml">
  <m:properties>
    <d:FileSystemObjectType m:type="Edm.Int32">0</d:FileSystemObjectType>
    <d:Id m:type="Edm.Int32">1</d:Id>
    <d:ID m:type="Edm.Int32">1</d:ID>
    <d:ContentTypeId>0x010049564F321A0F0543BA8C6303316C8C0F</d:ContentTypeId>
    <d:Title>an item</d:Title>
    <d:Modified m:type="Edm.DateTime">2012-07-24T22:47:26Z</d:Modified>
    <d:Created m:type="Edm.DateTime">2012-07-24T22:47:26Z</d:Created>
    <d:AuthorId m:type="Edm.Int32">11</d:AuthorId>
    <d:EditorId m:type="Edm.Int32">11</d:EditorId>
    <d:OData__UIVersionString>1.0</d:OData__UIVersionString>
    <d:Attachments m:type="Edm.Boolean">false</d:Attachments>
    <d:GUID m:type="Edm.Guid">eb6850c5-9a30-4636-b282-234eda8b1057</d:GUID>
  </m:properties>
</content>

as you see returned value contains GUID tag
