Cannot read property 'getReadModeConfig' of undefined

Question

I am getting these three errors on Sentry:

Cannot read property 'getReadModeConfig' of undefined
Cannot read property 'getReadModeExtract' of undefined
Cannot read property 'getReadModeRender' of undefined

I have a static page build using React@17.0.1 and NextJS@11.1.2 hosted on vercel.com. When I global searched these keywords, I have not found any such keyword being used in my codebase. These errors are breaking my website by invoking NextJS Error handler. Can anyone help me rectify these errors?

Thank You.

Sentry can catch any error that occurs in the page, including things like browser extensions or browser features.

As per What does these error means getReadModeConfig, getReadModeRender, getReadModeExtract it looks like the issue is related to the HeyTap Browser.

You can ignore such errors by configuring Sentry. In your case it could look something like this:

const sentryOptions = {
  ignoreErrors: [
    "getReadModeConfig",
    "getReadModeExtract",
    "getReadModeRender",
  ]
}

Cannot read property 'getReadModeConfig' of undefined
