Doesn't working properly on Heroku

[matheuschimelli]

First I would like to thank you for this buildback.

I would like to report a bug that i found when i was trying to deploy the heroku-playwright-buildback.
Some important infos:

• Node v17.6.0
• Npm v8.5.1
• Running on Heroku
  I'm using Typescript as well.

What's happening is that when i deploy heroku-playwright-buildback it doensn't work. However when i use the puppeteer buildpack https://github.com/jontewks/puppeteer-heroku-buildpack.git my app works.

I'm suspecting there is a bug but I don't know where it is.

Same issue here. @matheuschimelli are you using yarn? i found that the demo broke when using yarn as that is what we are trying to get to work on our end.

@mxschmitt any thoughts on how to get the demo/buildpack to work with yarn?

Yes. I'm using Yarn. However, i also tried with npm and i got that error.

@matheuschimelli I found that it wasn't related to yarn but the newer version of "playwright-chromium" (or similar).

try hardcoding your package.json value for "playwright-chromium" or similar to 1.15.0. the newer versions seem to have a dependency called "playwright-core" which don't seem to play nicely with the build pack as far as I can tell

Interesting. Thanks for the tip. I will try it later.

I'm using https://github.com/jontewks/puppeteer-heroku-buildpack.git with playwright and it works like a charm as well.

Hey guys, so was very frustated at this problem as I had it too, am using Yarn.
I followed your advice, downgraded to 1.15.0 and it works, thanks.
Hopefully a proper fix can be found some time.

Yes this is sad! But i have hope that one day everything will be better and all of us that are facing issues will have everlast happiness.

This just bit us after we upgraded our playwright-chromium package from 1.13 to 1.21. Glad this thread was here to point the way and hope this gets fixed soon.

Is there any way to make this work using playwright-python??

Hi, trying to bring this issue back to light.

Using the Python version of Playwright and it seems to compile successfully

But getting this in the logs

I also have this issue - I've worked on this for 2 days straight and can't seem to solve it.

I've tried to specify a specific verion:

 npm i [email protected]

I've also tried using a different buildpack

https://github.com/jontewks/puppeteer-heroku-buildpack.git

I've ensured that these buildpacks come before the heroku/nodejs one.

The issue I cannot seem to navigate is:

browserType.launch: Executable doesn't exist at /app/.cache/ms-playwright/chromium-1019/chrome-linux/chrome

app.json

{
  "buildpacks": [{ "url": "heroku/nodejs" }],

  "environments": {
    "test": {
      "stack": "heroku-20",
      "addons": ["heroku-postgresql:in-dyno"],
      "buildpacks": [
        { "url": "https://github.com/mxschmitt/heroku-playwright-buildpack" },
        { "url": "heroku/nodejs" }
      ],
      "scripts": {
        "test": "npx playwright test"
      }
    }
  }
}

I also have a playwright.config.ts setup from the playwright init command.

However removing this doesn't seem to effect the error.

Going back to basics this morning - I managed to get it working 🎉

app.json

{
  "buildpacks": [{ "url": "heroku/nodejs" }],
  "addons": ["heroku-postgresql:standard-0"],

    "test": {
      "stack": "heroku-20",

        { "url": "heroku/nodejs" }
      ],
      "env": {
        "PLAYWRIGHT_BUILDPACK_BROWSERS": "chromium,firefox"
      },
      "scripts": {
        "test-setup": "npx playwright install",
        "test": "npx playwright test"
      }
    },
    "review": {
      "addons": ["heroku-postgresql:hobby-dev"]
    }
  }
}
