Issue facing while including more than one start and stop commands

Your question

I was executing sitespeed scripts to capture response times. When I tried to run script with including more than one start and stop commands i.e.,
[ await commands.measure.start('');
await commands.measure.stop(); ]

in a script file, I am getting an error. I was not getting with previous version, with updated latest version only I am getting this error.

ERROR: Caught error from Browsertime TypeError: result[resultIndex].files.screenshot[runIndex] is not iterable
at BrowsertimePlugin.processMessage (file:///usr/src/app/lib/plugins/browsertime/index.js:430:76)

Command:
docker run --rm -v "$(pwd):/sitespeed.io" sitespeedio/sitespeed.io XXX.js --multi --viewPort 1786x708 --maxLoadTime 180000 --video=false --visualMetrics=false --visualElements=false --browsertime.screenshot false --browsertime.screenshotLCP false --browsertime.screenshotLS false --plugins.remove screenshot --plugins.remove har -n 1 -b chrome

Script:

await commands.addText.byId('XXX', 'username');
await commands.click.byXpathAndWait("");
await commands.addText.byId('XXX', 'password');
await commands.measure.start('Test1');
await commands.click.byXpathAndWait("");
await commands.measure.stop();
await commands.wait.byXpath("", X0000)

await commands.measure.start('Test2');
await commands.click.byXpathAndWait("");
await commands.click.byXpathAndWait('');
await commands.measure.stop();

Start with lib/plugins/browsertime/index.js around line 430 and reproduce the failure using the supplied Docker command and script containing two measure.start/stop pairs. Compare this behavior with the previous version if available, then verify that multiple measurements complete without the screenshot iteration error under the stated screenshot and plugin options.
