Cypress adds underscore while running tests and fails with error - Error: Cannot match any routes. URL Segment: '__'

See following in console logs -

An unhandled error occurred Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: '__'

Following is the cypress.json -

{
    "baseUrl": "http://localhost:4200",
    "fileServerFolder": ".",
    "fixturesFolder": "./src/fixtures",
    "integrationFolder": "./src/integration",
    "modifyObstructiveCode": false,
    "pluginsFile": "./src/plugins/index",
    "supportFile": "./src/support/index.ts",
    "video": false,
    "videosFolder": "../../dist/cypress/apps/e2e/videos",
    "screenshotsFolder": "../../dist/cypress/apps/e2e/screenshots",
    "chromeWebSecurity": false,
    "testFiles": "**/test.feature",
    "numTestsKeptInMemory": 0,
    "env": {
        "auth_username": "1111",
        "auth_password": "2222",
        "RETRIES": 2
    }
}

This is what I see when test runs in cypress window -

http://localhost:4200/__/#/tests/integration\maintenance\service\test.feature

@jennifer-shehane , I followed https://github.com/nrwl/nx/issues/1276 to setup the tests. We are following feature files (cucumber) pattern in nrwl mono repo. Just in case that gives any pointers.

What else can I provide so that you can reproduce it on your side. Can try setting up a new project and share the repo, may be. We are halfway using cypress and now this issue is completely blocking.

This is happening to me todat angular 13 and cypress/schematics 1.6.0 , cypress 9.6.0.

Step1: Create a brand new angular project with routing - call this my-cypress-app

Step 2: ng add @cypress/schematic

Step 3: ng serve

Step 4: ng run my-cypress-app:cypress-open - click on the spec file, F12 in the another chrome window and this exact error
