Fixed an issue to render the error properly in ui

[ryanhopperlowe]

nit: we have a helper (import { cn } from "~/lib/utils") that will clean up any duplicates in your styles + clean up the code a bit.

Also can you use a preset color from the tailwind.config.ts instead of text-gray-500 (I'm guessing you want something like text-muted or text-secondary-foreground but use whichever color makes most sense to you)

                    className={cn(`text-sm mr-2`, {
                        "text-destructive": !source.runID && source.error,
                        "text-muted": source.runID || !source.error,
                    })}
