HI Manisha,
Ensure that you have  added the URL to CSP Errors whitelist using a wildcard like this: https://*.forcecontentuser.com

Also there is a known issue with the lightning:map usage which is worth checking: https://trailblazer.salesforce.com/issues_view?id=a1p3A000001FSlqQAG

Hi Vijay,

You should implement HttpCalloutMock class when testing with Web servoce callouts in Apex.


Please modify your test class in following manner:
private class Test_class {

    private class RestMock implements HttpCalloutMock {
        public HTTPResponse respond(HTTPRequest req) {
            String fullJson = 'your Json Response';
            HTTPResponse res = new HTTPResponse();
            res.setHeader('Content-Type', 'text/json');
            return res;
    static testMethod void service_call() {
        Test.setMock(HttpCalloutMock.class, new RestMock());
        //your webserive call code

Hi Everyone,

I need some help. I have recently turned on the domain in the Sandbox. I have uploaded the logo and set the URL for the banner. When I go to the Salesforce login page using the domain URL, everything looks great but when I log in and log out from Salesforce, I don't see my company's Logo anymore.

Logo Dimensions:
Width: 180 px
Height: 113 px
Size: 9.32 KB

Login Salesforce with Logo


Login Screen Without Logo

Hi Ankit,

In the above link there is a similar issue where it is showing a broken image in login screen.

Can you try checking the below answer that is selected as best answer in above link once?
One troubleshooting effort I would undertake is to clear your browser cache - or try another browser you haven't used yet. This will help rule out the browser as a cultprit. Salesforce loves to cache data.

Clear Chrome Browser Cache (https://support.google.com/accounts/answer/32050?co=GENIE.Platform%3DDesktop&hl=en)
Clear Firefox Broswer Cache (https://support.mozilla.org/en-US/kb/how-clear-firefox-cache)

Then, I would jump to the Brand Asset Files

Make sure your logo file is there.

Then, click on the logo. Once you get to the next page - click view. This will take you to the record page to see if the image is showing there.

CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY:pc_rollup: execution of AfterUpdate

caused by: System.NullPointerException: Attempt to de-reference a null object


It happens when an integration tried to run a background job. Some of the accounts it is updating do sync but the ones that fail have this error. 
Best Answer chosen by Samir Mahtani 4
ShivankurShivankur (Salesforce Developers) 
Hi Samir,

This error is caused by a line of code that is trying to use an object that has not been instantiated, or an object's attribute that has not been initialized.

If the field Site was left empty, it will generate the error message as(System.NullPointerException: Attempt to de-reference a null object) shown by the operation performed with the Integration done.

In order to avoid such issues, you should write try-catch blocks in your apex code and check if any of the fields which are required to be not null to succeed the operation. The exception can be smoothly handled with this technique.Also, additional logic checks in the code could avoid the records which are not eligible for update(which don't have the required fields) as well.


The catch block handles the raised exception. Then the finally block executes. It writes a debug message and closes the stream writer, which frees any associated resources.

Hope above information helps, Please mark as Best Answer so that it can help others in the future.

What validation rule should I write for this?

Thank you for answering my question, but somehow that validation rule didn't work. Although I tried another one and it worked for me. 

( IF(ISBLANK(Field_A__c),0,1) + IF(ISBLANK(Field_B__c),0,1) ) > 1

I wanted to try the data import wizard with an Excel data that I converted to a CSV. When I add the CSV I got the problem that The columns are not seperated by comma but semicolon. What datatype or other option can I use so the problem does not occure?

Hi Jonathan,

This are consideration while importing data from CSV file in salesforce.

Most probably  your excel setting changes the delimiter to semi-colon (;) instead of comma (,). To resolve this issue:

1. Go to your file and right click on it.
2. Select Open with and select notepad
3. Once the file open in notepad, click on the Edit Tab.
4. Select replace
5. On the "Find what" field enter the value (;) semi-colon
6. On the "Replace with" field enter the value (,) comma
7. Click on the Replace all button.
8. Save the file and add the .CSV on the end of the file name.

Once done with the last step, don't open again the save file on excel. This will ensure that the delimiter of the file is save as comma delimited. The file should be good for import. Please let me know if this answer your query or you can mark it as solved.

The problem may be in the quotes. You should use single quotes within double-quotes. Since, you just need to evaluate as a string which is style and should work with it.

HI Vijay,
I see you also reached out on https://github.com/forcedotcom/lwc-dev-server-feedback/issues/3

Also, recommend checking https://github.com/nodejs/node-gyp/issues/1136

Can you confirm that you have reinstalled sfdx and npm?

You can also try the below approach:
>Install node gyp by running 
npm install -g node-gyp
>In command prompt or whatever command-line interface you use.
And then after that, you can run 
npm install --global --production windows-build-tools

Hope this helps to fix the problem.
