Can't find the driver

Greetings,

I’ve been using Playwright Sharp and it’s been working really well on my local development machine. However, when I try to deploy my application to one of my servers, I am sometimes greeted with the following exception:

Unhandled exception. System.AggregateException: One or more errors occurred. (Driver not found in any of the locations.)
 ---> PlaywrightSharp.PlaywrightSharpException: Driver not found in any of the locations.
   at PlaywrightSharp.Transport.Connection.GetExecutablePath() in /home/runner/work/playwright-sharp/playwright-sharp/src/PlaywrightSharp/Transport/Connection.cs:line 270
   at PlaywrightSharp.Transport.Connection.GetProcess(String driverExecutablePath) in /home/runner/work/playwright-sharp/playwright-sharp/src/PlaywrightSharp/Transport/Connection.cs:line 233
   at PlaywrightSharp.Transport.Connection..ctor(ILoggerFactory loggerFactory, TransportTaskScheduler scheduler, String driverExecutablePath, String browsersPath) in /home/runner/work/playwright-sharp/playwright-sharp/src/PlaywrightSharp/Transport/Connection.cs:line 74
   at PlaywrightSharp.Playwright.CreateAsync(ILoggerFactory loggerFactory, TransportTaskScheduler scheduler, String driverExecutablePath, String browsersPath, String debug) in /home/runner/work/playwright-sharp/playwright-sharp/src/PlaywrightSharp/Playwright.cs:line 109

This exception is thrown when I call CreateAsync() or InstallAsync() as well. Here’s what I’ve tried so far:

• Call Create and Install as the first line of code in my application, this only threw the above exception
• Attempt to build and dotnet publish my application so the build-time Playwright tools could do their magic
• Ran npx playwright install to install any missing drivers. This returns without any errors, but the exception still occurs

The %USERPROFILE%\AppData\Local\ms-playwright contains the following directories:

Playwright did initially work on this server for a while, but after a redeploy without any significant code changes, it randomly stopped working. Is there anything I’m missing here?

Thanks!

@andreasvatne We’ve published a significant new release this morning - now available as Microsoft.Playwright on NuGet. It should also fix the problem you were seeing.

@kblok Do you know when a new release including the dotnet publish fix will be out?
