I have written code to upload the file in SharePoint online .. but while upload the page gets refreshed .. Please help .

Code -

      .files.add(fileContent.name, fileContent, true)
      .then(f => {
        f.file.getItem().then(item => {
            Title: "A Title",

Looks likely that your document library does not have a Description field, i.e. a field with the internal name "Description". PnP wants you to specify the internal name, not the display name of the fields to set.

Does the field perhaps have a different internal name and only the display name is "Description"? Try checking by going into the List Settings page and clicking on your "Description" field - in the address bar, there is a "&Field=XY" parameter, where XY is your (encoded) internal name of the field.

  • Thank you . I have document library with content type . How to upload document library with .. content type metadata ? Please help . Commented Feb 1, 2019 at 6:09
  • I currently don't have a possibility to test it, but did you try either setting a property "ContentType" or "ContentTypeId" to the unique ID of the Content Type (which has a form similar to 0x010100XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX)?

The Problem is on your field name which You passed here..Just creating new Document library then You will add new columns What You want and after you can give that exact field/column name without changing and then finally pass it in your code.
