postInteractionWait does not work anymore on v6.1.1 (puppeteer)

[ttl15]

Hello,

Looks like v6.1.1 update
"puppeteer": "^14.2.1",
to
"puppeteer": "^15.4.0",

when postInteractionWait on backstop.json file is greater than 0 (ie 3000)

backstop will throw an error below

Puppeteer encountered an error while running scenario...
TypeError: page.waitFor is not a function

steps to reproduce

use backstop v6.1.1
create a new project
backstop init
backstop reference

no errors so far

now change postInteractionWait in backstop.json file to something other than 0 (ie 3000)
run backstop reference again

error msg

SCENARIO > BackstopJS Homepage
Puppeteer encountered an error while running scenario "BackstopJS Homepage"
TypeError: page.waitFor is not a function
Browser Console Log 0: JSHandle:BackstopTools have been installed.

FWIW rolling back to backstopjs 6.1.0 got me around this. Saw this in the log output:

waitFor is deprecated and will be removed in a future release. See https://github.com/puppeteer/puppeteer/issues/6214 for details and how to migrate your code.

For those running into the issue and finding this issue - there's now a PR to fix this (#1441) but you might need to fix this yourself if you have a puppet/clientAndHoverHelper.js generated by a previous version of backstop.

Have a look here for inspiration.
