Browser: 'chrome' was not found on your system or is not supported by Cypress.

Current behavior

We are building a docker image with cypress, chrome and all the spec files (using cypress/included). This image is run from our instance of Gitlab CI automatically. Only the CYPRESS_BASE_URL environment variable and the name of the spec file are passed to the docker run command line.

Sometimes, very rarely, we have the following error:

> cypress run --headless --browser chrome --reporter cypress-multi-reporters --reporter-options configFile=reporter-config.json "--spec" "cypress/integration/interview.spec.ts"

Can't run because you've entered an invalid browser name.
Browser: 'chrome' was not found on your system or is not supported by Cypress.
Cypress supports the following browsers:
- chrome
- chromium
- edge
- electron
- firefox
You can also use a custom browser: https://on.cypress.io/customize-browsers
Available browsers found on your system are:
- firefox
- electron

The system automatically retry failed jobs and it works the second time.

Desired behavior

Not crash.

Versions

Cypress 5.3.0 inside a Docker running on a Ubuntu 20.04.

Seeing the same inconsistent behavior in a image built off of the cypress/browsers:node10.16.0-chrome77

Just thought that I'd reiterate that I'm experiencing the same issue using the official cypress Docker image, specifically "cypress/included:5.3.0".

The command I'm running in the Docker container is as follows:

NODE_ENV=test $(npm bin)/cypress run --config video=false --browser chrome --headless --record --key <my_key> --parallel --ci-build-id $BUILD_NUMBER

Below is the error I'm receiving. Like the others, it happens very inconsistently. Very perplexing given Chrome comes preinstalled with the "cypress/included:5.3.0" docker image.

cypress_1 | Can't run because you've entered an invalid browser name.
cypress_1 | Browser: 'chrome' was not found on your system or is not supported by Cypress.
cypress_1 | Cypress supports the following browsers:
cypress_1 | - chrome
cypress_1 | - chromium

cypress_1 | You can also use a custom browser: https://on.cypress.io/customize-browsers
cypress_1 | Available browsers found on your system are:

The docker container is built and run by a Jenkins server running on Ubuntu 18.04.

I think this issue belongs on the https://github.com/cypress-io/cypress-docker-images instead of this repo

[rachelruderman]

I can confirm that this error also (rarely) happens on cypress/included:6.3.0
