Scales parameter not showing in Manage Map Server Cache Tiles tool

[CoryDavis]

I'm attempting to recreate all tiles for a tile cache service using the Manage Map Server Cache Tiles geoprocessing tool. I've performed this operation successfully on other services before but this time my client recently upgraded to ArcGIS Pro v2.6.3 and now when I open the tool, the scale parameter is not visible.

This is a required parameter, so I cannot run the tool without specifying it. What is causing this behavior? Is there a workaround I can use to run the tile cache creation job?

Hello,

I initially saw this behavior when I was not pointing to a valid input. By any chance does this issue occur for your client on any other services?

You could try to run the tool in model builder or in the python window and see if that allows you to bypass this issue.
