axe-cli: "An error occurred while testing this page"

[DanielTripp]

Product: cli

Expectation: To print a list of accessibility violations to stdout.

Actual: No list of accessibility violations, or any evidence of a scan, appears on stdout. Instead, this appears:

DevTools listening on ws://127.0.0.1:54164/devtools/browser/8e985c0a-b6d8-46ba-aabd-592db8ed88a2
An error occurred while testing this page.
Please report the problem to: https://github.com/dequelabs/axe-core-npm/issues/

Motivation: I think that my "Expectation" is a design goal of axe-cli. Of course, I'm new to this, so I could be wrong.

axe-core version: 4.2.0, I think.  (That's what it says in my file C:\Users\dt\axe-cli-july-25-b\axe-core-npm\node_modules\axe-core\axe.js.  First line: "/*! axe v4.2.0".) 
@axe-core/cli: 4.2.2, I think.  (That's what it says in my file C:\Users\dt\axe-cli-july-25-b\axe-core-npm\packages\cli\package-lock.json: "version": "4.2.2".)

- Node version: v14.17.3
- Platform:   Windows  

I've attached my steps to reproduce as a copy-and-paste of my PowerShell console.

I don't know whether this is a bug or not. But I sure would benefit from some guidance. All suggestions welcome.

I have same issue with axe cli on Linux inside circleCI
node v14.10.0 (npm v7.20.1)
Running axe-core 4.3.1 in chrome-headless
I have run script against different pages and it always fails (previously it worked fine with same versions and same web pages) it looks like problem appeared with latest updates)

@DanielTripp if to use older version of chrome it works for me so I think issue appears only with latest chrome (axe cli works fine on chrome v 91.0.4472.164-1 but fails on 92.0.4515.107-1) also it passes if to change browser to firefox
Try:
axe www.deque.com --tags wcag2a --browser firefox

@AlexTolok Thank you - I tried firefox and it worked. I looked for older versions of Chrome for download and couldn't find them. But I'm okay with Firefox for now.

I think I have the same issue. With the --show-errors flag, this is what I get:

Thank you @dacohenii, I added --show-errors and I also got a message like that:
