Issue facing while including more than one start and stop commands

[sweety-18]

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();

Hi @sweety-18 what was your previous version and which is your current version? I want to check if browsers updated between the versions. I'm thinking maybe pages do not navigate to a new page when you click? Or if you watch the result, what do you see?

Hi @soulgalore, current version is sitespeed.io: 34.3.4. It is able to navigate, But in the end giving an error. Exact output:

What version were you using before?

Here's how you can help me so I can reproduce it: https://www.sitespeed.io/documentation/sitespeed.io/bug-report/

[sweety-18]

We were using 34.3.3 previously.

[soulgalore]

Can you try 34.3.5 or a later version? 34.3.4 disabled all LCP/CLS by default, so 34.3.5 fixed the LCP and CLS disabling screenshots better. Can you please share your configuration so I can try to reproduce it? My guess is then that it has something todo with the disabling of LCP/CLS if that what you do, but full configuration would help. Thanks!

I tried executing scripts with the updated version 34.3.7.

Can you please take a look at this issue, even after updating the version, I am not able to run with more than one start and stop commands.
