I am creating an SPFx solution to create folders with nested folders. This solution is working fine. but I want to attach some metadata to my folder. For this reason I have created a new folder content type and added few site columns to it. But I am not getting how to update the content type value while creating the folder. I am using below code for folder creation

private createFolder(folderUrl: string): Promise<any> {
    let customFolderCTId = "0x012000F1CF7BFF04CE7344891D1F19E91A18ED";
    const spOpts: ISPHttpClientOptions = {
      body: JSON.stringify({
    return (
      this.state.context.spHttpClient.post(folderUrl,SPHttpClient.configurations.v1,spOpts).then((r: SPHttpClientResponse) => {
        return r.json()
      }) as Promise<any>

Above code is giving me error as {"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":"The parameter ContentTypeId does not exist in method Add."}}

What is the resolution for this?

  • Can you share the folderUrl that you are using in your code ? – Gautam Sheth Oct 29 '18 at 14:21
  • let _folderUrl = clientCtx.pageContext.web.absoluteUrl + "/_api/web/folders/add('${libraryName}/${clientName}')"; – Mihir Oct 29 '18 at 15:12
  • Updating folder content type is available through REST api? – Mihir Oct 29 '18 at 15:18

You need to modify your existing endpoint include the details of the created folder by including select and expand OData operator as below:


Once you do this, you can get the ID of the created folder item. After that, its a simple update operation to the list item.

The code will be somewhat as below:

let _folderUrl = this.context.pageContext.web.absoluteUrl + 

const body: string = JSON.stringify({});

    body: body
  }).then((response): Promise<void> => {
    return response.json();
  .then((item): void => {


    // get the created folder item Id
    var itemId = item["ListItemAllFields"]["ID"];

    var folderItemUrl = this.context.pageContext.web.absoluteUrl + 
    "/_api/web/lists/getByTitle(`${libraryName}`)/items('" + itemId +"')";

    // use the list item entity type full name

    const updateBody: string = JSON.stringify({
      "__metadata": {"type":"SP.Data.`${libraryName}`Item"},

      headers: {
        'Accept': 'application/json;odata=verbose',
        'Content-type': 'application/json;odata=verbose',
        'odata-version': '',
        'IF-MATCH': '*',
        'X-HTTP-Method': 'MERGE'
    }).then(d =>{
      console.log("success updating folder content type");

  }, (error: any): void => {
  • Thanks for the update. I will try this and let you know. – Mihir Oct 29 '18 at 17:33
  • @Mihir - any update on this ? I tried it at my end was able to make it work :) – Gautam Sheth Nov 3 '18 at 20:04
