[Bug]: could not start playwright: please install the driver (v1.47.0) and browsers first: %!w(<nil>) when trying to run on CloudRun

Environments

• playwright-go Version: github.com/playwright-community/playwright-go v0.4700.0
• Browser: any
• OS and version: macOS

Bug description

Hi, I am running golang project which uses playwright. Everything works locally and I can use playwright and it installs and run Browser and gets to URL no problem

• running this in docker container To build locally I use
• docker build -t api:1 .
• docker run -d -p 8080:8080 api:1
• then I can make requests to my go backend which runs playwright

Problem is when I deploy this to Google Cloud Run

• docker build -t gcr.io/my-project/api:1 .
• docker push gcr.io//my-project/api:1
• gcloud run deploy --image gcr.io//my-project/api:1 --platform managed

this deploys my api and API works fine. the problem is that when I make a request to my resolver where I start playwright

pw, err := playwright.Run()
    if err != nil {
        log.Printf("could not start playwright: %v", err)
        return nil, errors.New("Error contact support.")
    }

I get this error back could not start playwright: please install the driver (v1.47.0) and browsers first: %!w(<nil>)

To Reproduce Steps above in bug description

Go project setup My setup is golang + graphql

• my resolver is in gql-user folder
• function name is func (r *Resolver) GetTestData(p graphql.ResolveParams) (interface{}, error) {
• import is "github.com/playwright-community/playwright-go"
• I am using docker file https://github.com/playwright-community/playwright-go/blob/main/Dockerfile.example with go version 1.22.1

As I mentioned this works fine locally but as soon as I push the container to Cloud Run I am getting the error that could not start playwright: please install the driver (v1.47.0) and browsers first: %!w(<nil>)

Maybe the version in go.mod is not v0.4700.0 when you build the container image? A rebuild is required every time the playwright-go major or minor version number is updated.

it was couple things

• node not being installed in docker container on cloud run, (local docker had to use some cached version probably)
• then another thing was that I have not done this on my app start

  if err := playwright.Install(&playwright.RunOptions{
      Browsers: []string{"chromium"},
      // DriverDirectory:     "/tmp/playwright",
      SkipInstallBrowsers: false,
      Verbose:             true,
  }); err != nil {
      log.Fatalf("could not install playwright here: %v", err)
  }

As I thought it will be handled by docker file but how wrong I was.
