What are you trying to accomplish
I ran a scripted run for 3 iteration. In the report, I am not seeing the waterfall getting loaded. I can see below error in the console
Uncaught (in promise) SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at index.html:137:24
What browser did you use?

Research direction
Start by reproducing the three-iteration scripted run against https://demoqa.com/ in Chrome and inspect the generated report at index.html:137, where JSON.parse reports an unexpected end of input. Compare runs that show the waterfall with runs that do not, using the console error as the initial lead. Done means the report loads the waterfall consistently without this parsing error.
