Custom Sorting with multiple visuals on the page causes an error

Hi, ChrisWilliams 

In response to your query, my initial thought revolves around the issue of custom visual object interactions. You might consider manually editing these interactions to ensure there are no unintended interactions between the visuals.

For further details, please refer to:

Change how visuals interact in a report - Power BI | Microsoft Learn

...
   let allowInteractions = options.host.hostCapabilities.allowInteractions;
   bars.on('click', function(d) {
       if (allowInteractions) {
           selectionManager.select(d.selectionId);
           ...
       }
   });

For further details, please refer to:
https://learn.microsoft.com/en-us/power-bi/developer/visuals/visuals-interactions#set-interactive-permissions

Regarding the definitions of sortDirectionA and sortDirectionB, I currently do not see their definitions directly. Additionally, since you have implemented an external loop that repeatedly executes this operation, I recommend checking your visual object's configuration file to confirm the definitions and default values for sortDirectionA and sortDirectionB.

Lastly, here is the documentation for diagnosing exceptions, which I hope will be helpful to you:
