LWC Custom Permission – Troubleshooting Custom Permission Check Always Returning Undefined

custom-permissionlightning-web-components

I am trying to disable a button on an LWC based on a custom permission, but I cannot seem to make it work. Here is the code involved:

js controller (let's call it actions):

import hasResetSecQuestionsPermission from '@salesforce/userPermission/Reset_Security_Questions';

export default class actions extends LightningElement { 
  get disableResetSecQuestionsButton() {
    return !hasResetSecQuestionsPermission;
  }
}

Html lightning button:

<lightning-button
  variant="neutral"
  name="resetSecurityQuestionsButton"
  data-id="ResetSecurityQuestions"
  label="Reset Security Questions"
  title="Reset Security Questions"
  onclick={handleClick}
  disabled={disableResetSecQuestionsButton}
  class="slds-align_absolute-center"
></lightning-button>

I am aware that in this case hasResetSecQuestionsPermission should return undefined if the running user has not been assigned the permission, and true if they have. But it seems to return undefined for me even if I have the permission. I have checked I have it for sure by running

System.debug(FeatureManagement.checkPermission('Reset_Security_Questions'));

anonymously and it returns true.

Any ideas what could be wrong?

Best Answer

Seems like error in the import statement, it should be @salesforce/customPermission

Lightning Web Components – Fix getRecord and getFieldValue Returning Undefined Values

define a track variable

@track alertdata;

getRecord is as follows:

  @wire(getRecord, { recordId: '$recordId', fields})
    requete({error, data}){
      if(data){
        this.alertdata = data;
      }else if(error){
        console.log('requete error', JSON.stringify(error)); // Never rendered
      }
    }

alertID method is as follows:

 get alertID() {
    console.log(this.alertdata); 
    return getFieldValue(this.alertdata, ALERT_FIELD);
  }

LWC – Fixing Undefined JSON Parse Responses in Apex

You need to fetch the values like this:-

handleClick(){
  returnVal({})
    .then(result => {
      let valJson = JSON.parse(JSON.stringify(result));
      valJson.data.forEach(element => {
        console.log(element.test1);
      });
  }
}

because valJson is having an attribute called data which is of array type. So you need to itearte on it find the values.

You were trying to do valJson[0] which is not valid.

UPDATE

As per comment, method is returning stringified value, so slight change in above code. changed let valJson = JSON.parse(JSON.stringify(result); to let valJson = JSON.parse(result);

handleClick(){
      returnVal({})
        .then(result => {
          let valJson = JSON.parse(result);
          valJson.data.forEach(element => {
            console.log(element.test1);
          });
      }
    }

Another Update

I have tried replicating your problem in my org. I created a method as below:-

@AuraEnabled
    public static string jsonReturn(){
        string value = '{"data":[{"test1":"079","test2":"00100","test3":"4352","test4":"543","test5":"234642","test6":2719,"test7":"hello","test8":"0444542","test9":"test hi one"},{"test1":"24566134","test2":"0102","test3":"66543","test4":"244549","test5":"2666549","test6":24525,"test7":"once","test8":"595552","test9":"test hi two"}]}';
        return value;
    }

then in my lwc js file

handleJSON() {

        jsonReturn().then(res => {
            console.log(res);
            console.log(JSON.parse(res));
            console.log(JSON.parse(res).data);
            JSON.parse(res).data.forEach(element => {
                console.log(element);
            });
        }).catch(error => {
            console.log(error);
        })

    }

and got this in log:-
