spHTTPClient.POST not working for Taxnomy Field on SPFX WebPart with no error

Asma Rhouma 41 Reputation points

Hi All,

I need to update a ListItem from my spfx.
****Solution 1** : uses pnpjs**

const i = await list.items.getById(itemId);  
      // execute the update call  

==> error "throttle limit exceeded" as the the list have more than 12 MetaDataField (Taxonomy).

Solution 2 : use the REST API

const restAPI = webAbsoluteUrl +  `/_api/web/lists/getByTitle('${listTitle}')/items(${itemId})?select=Title,Document_x0020_Language`;  
        return context.spHttpClient  
          .post(restAPI, SPHttpClient.configurations.v1, {  
            headers: {  
              "content-type": "application/json;odata.metadata=none",  
              "if-match": _etag,  
              "x-http-method": "MERGE",  
            body: JSON.stringify({  
              /*  __metadata: {  
                type: "SP.Data.TAX_xxxxxItem",  
              Title: "Update_Title_ForTest_10",  
              Document_x0020_Language: {  
                // __metadata: { type: "SP.Taxonomy.TaxonomyFieldValue" },  
                TermGuid: "311c9e5f-d7df-4d0d-9c78-05d3e8100d29",  
                WssId: -1,  
                Label: "English",  

          .then((response) => {  
            if (response.status === 204) {  
              alert("successfully Updated");  
            } else {  

==>using this code, the response is always succeeded and the Title Field is updated but nothing is changed for the taxonomy Field
I think this is is because the number of lookup fields is more than 12( the limit) but I can't change this structure as the native Microosft Editform is working

Any help would be greatly appreciated!

    Hi @Asma Rhouma
    Per my test, you can refer to following code to update multi value taxonomyfield

    const listWeWantToUpdateMulti = pnp.sp.web.lists.getByTitle('ListWeWantToUpdateTitle');  
    // Example of a term string.  
    // You can also use the Id returned in rest calls instead of the full label  
    const termString = '-1;#SomeTerm|02ee415b-99c4-448b-8727-7daa2a4a281;#-1;# SomeOtherTerm |0e2f40d9-09ac-406e-b102-630e8dadade6;';  
    // If the name of your taxonomy field is SomeMultiValueTaxonomyField, the name of your note field will be SomeMultiValueTaxonomyField_0  
    const multiTermNoteFieldName = 'SomeMultiValueTaxonomyField_0';  
        .then((entityTypeFullName) => {  
                .then((taxNoteField) => {  
                    const multiTermNoteField = taxNoteField.InternalName;  
                    const updateObject = {  
                        Title: 'Item title', // Only included as an example  
                    updateObject[multiTermNoteField] = termString;  
                    listWeWantToUpdateMulti.items.add(updateObject, entityTypeFullName)  
                        .then((updateResult) => {  
                        .catch((updateError) => {

    Hi @RaytheonXie_MSFT ,
    I tested the solution that you posted but it doesn't work and getListItemEntityTypeFullName was not recognized. but I tested the code without it and it doesn't work.
    The good News is that I found the solution : I used the batching https://pnp.github.io/pnpjs/sp/items/

    So the solution is :

     import "@pnp/sp/batching";  
      const [batchedSP, execute] = sp.batched();  
             .validateUpdateListItem([{Document_x0020_Language : "English|311c9e5f-d7df-4d0d-9c78-05d3e8100d29;"},{Document_x0020_Status : "DRAFT|c25c9e5f-d77f-4a1d-7c79-05d3e8100d21;"},{Title:  "Test Update"}]);  
           await execute();
