I've run into lots of issues with running tests with results from BrowserStack that look like this:

 error: Cypress could not run any of the specs in the build since an exception occurred. The stacktrace of the error is given below:

I suspect that this might be happening because I build the test package using a Docker container on Linux, but the machine running the tests uses Windows.
Using cached packages for one OS and then trying to unzip them onto another OS is not going to work a lot of the time. I don't think the tool should be attempting to do this, or there should be some kind of opt-out.

Hey @bingnz ,

Thanks for bringing up this issue, while we look into this issue, if possible can you please share the list of npm_dependencies that you are using for your build?

Meanwhile, to circumvent this issue can you try setting cache_dependencies to false inside run_settings of your browserstack.json. Let us know if that solves your issue for now.

For more info, please visit this link.

Hi @pranavj1001. my dependencies are:

      "@aws-sdk/client-dynamodb": "3.47.0",
      "@cypress/webpack-preprocessor": "5.11.1",
      "aws4": "1.11.0",
      "chai-datetime": "1.8.0",
      "cypress": "9.4.1",
      "cypress-fail-on-console-error": "2.1.3",
      "dayjs": "1.10.7",
      "del": "4.1.1",
      "faker": "5.5.3",
      "inversify": "5.1.1",
      "lodash": "4.17.21",
      "minimist": "1.2.5",
      "mssql": "7.3.1",
      "mysql2": "2.3.3",
      "node-vault": "0.9.22",
      "reflect-metadata": "0.1.13",
      "ts-loader": "6.2.2",
      "tslib": "2.3.1",
      "tsconfig-paths-webpack-plugin": "3.5.2",
      "typescript": "4.6.2",
      "webpack": "4.46.0"

If I use cache_dependencies false, it seems that the build just hangs (or at least takes well over an hour). I don't have any of these problems locally.

Hello @bingnz

Would it be possible for you to reach out to us (for the same issue) via support@browserstack.com?

Thanks! Yes I've already done so a few days ago. I've had a few different problems, sometimes I get the npm issues as above and sometimes the build runs for two hours and then fails.
