Started seeing error: Capybara::Apparition::CDPError: Invalid parameters

[hemaldev]

Hi there, firstly thanks for an incredible gem, we're a non-profit based in South India and your work with this gem is really helping us with our work.

We've run into an issue and we were wondering if you would be able to guide us. We're running a job on Heroku to do some work on a partner website which doesn't have an API. Recently when running this job we've started seeing the error Capybara::Apparition::CDPError: Invalid parameters. Below is the full stack trace...

Having played around with our codebase, we're not sure how to progress to debug further and was hoping you could provide some guidance. We're not sure if it's a Chrome issue, an issue with the response from the partner website, Capybara, or Apparition – despite the error message.

Any pointers would be much appreciated. Please let us know if we can provide any further information 🙏

This happens when we do

@browser.find_field("join_neu_email_field").set(USER_NAME)
@browser.find_field("join_neu_password_field").set(PASSWORD)

Closing this as we swapped to Cuprite

@hemaldev Ok -- If you do try it again with apparition please set an environment variable DEBUG=v and then provide the log around the error.
