Selecting palette in Covariate Bars portion of Heat Map Display Properties for throwing error.

[jmelott]

Clicking a palette does not change the colors assigned to the covariate breakpoints.
The following error appears in the console:
ngchmWidget-min.js?v=fe1a4448dce2762009386be05bc68ec8:707 Uncaught TypeError: Cannot read properties of null (reading 'value')

at HTMLDivElement.C (ngchmWidget-min.js?v=fe1a4448dce2762009386be05bc68ec8:671:355)

Steps to repeat:
Open a map with a continuous covariate bar.
Open developers console.
Click gear menu to open Heat Map Display Properties dialog box.
Click the Covariate Bars tab.
Select a continuous covariate in the Covariate Bar dropdown.
If the Bar type is not already Color Plot, then switch it to Color Plot.
Click on any of the pre-defined color palettes at the bottom of the dialog.
Result: The error above appears in the console and no breakpoint colors are selected.
Desired result: Breakpoint colors should change to match palette definition that was clicked on similar to how this works on the Heat Map Colors tab.
