Why am I Receiving "A custom JavaScript error caused an issue loading your dashboard"?

[kamlesh_vaghela]

Hello Splunkers,

I'm sharing a temporary solution for "A custom JavaScript error caused an issue loading your dashboard"  popup message when your dashboard has any console errors.

 

 

Basically, this error message indicates that there is some javascript error during the execution of the script and you can easily check by doing inspect as well. 

Before applying this solution I suggest identifying the javascript error and resolve in case there is scope.  Bcoz it may impact the logic. 

If you are trying to resolve this issue and taking time then this temporary solution is good for you 🙂 

This is a Javascript-based solution, which overrides the popup container and makes it empty whenever it tries to populate with the error message.

 You can put this JS Code in your dashboard's Custom JS file or create the common file and use it in multiple dashboards.

require([
    'underscore',
    'jquery',
    'splunkjs/mvc',
    'splunkjs/mvc/simplexml/ready!'
], function(_, $, mvc) {

    console.log($('[data-test="layer-container"]'));
    
    $('[data-test="layer-container"]').on('DOMSubtreeModified', function(){
        console.log('changed two');
        $('[data-test="layer-container"]').empty();
    });

    $('[data-test="layer-container"]').empty();
});

I have tried this with Splunk Enterprise Version: 9.0.2 Build: 17e00c557dc1. In case you find any difficulties please let us know.

I hope this will help you.

Happy Splunking

Thanks

Can you please try this? Now no other code will be impacted.

require([
    'underscore',
    'jquery',
    'splunkjs/mvc',
    'splunkjs/mvc/simplexml/ready!'
], function (_, $, mvc) {
    $('[data-test="layer-container"]').on('DOMSubtreeModified', function () {
        console.log('changed two');
        if ($('[aria-label="Toast messages container"]')) {
            console.log("Toast messages container cleared");
            $('[aria-label="Toast messages container"]').empty();
        }
    });
});

Please check & confirm with your code.

Thanks

Hi @kamlesh_vaghela ,

This solution worked. Thanks!

Hi @spkriyaz , Could you please share the detailed step by step procedure to apply this solution? 

[kamlesh_vaghela]

Glad to help you @spkriyaz

Hi @kamlesh_vaghela ,

I used your javascript it restricted the error popping out from the dashboard but it impacts the filter that are in the dashboard. The filter dropdown doesn't work and after few clicks the filter vanishes. I have copied the console details below.

Hello @kamlesh_vaghela , I'm tried your solution, but this script also disables drop down list from input of dashboard. Sometimes make this input disappear from dashboard.

Do you have any idea about it. Or Have you resolve "A custom JavaScript error caused an issue loading your dashboard."?

I'm looking forward to hearing from you. 

Thank you very much.

Can you please share your sample XML and JS code?

I am using your JavaScript code and embedding it into this XML.

When I insert your JavaScript code, all the dropdowns and mutilselect of the inputs do not display. Almost all dashboards are affected by this issue.

Here is my XML

Hi @kamlesh_vaghela,

I have this problem on Splunk Cloud, have you any idea on how to use your solution in this environment?

Ciao.

Giuseppe

[VatsalJagani]

For your custom App, yes.

For third-party Apps, I don't think so. Unless Splunk Support is willing help in anyway.

[gcusello]

Hi @VatsalJagani ,

I trid to add the js but it wasn't possible to upload it in Splunk Cloud.

Ciao.

You can solve the error by entering the configuration panel-server configuration -internal libraries -and enable old versions
