Docker Failed to launch browser

[therealsras]

I was running on Windows , locally testing fine, not running docker, just dotnet watch

This is issue when I compose to docker and try from docker.

{ "title": "Failed to launch browser! /app/\\puppeteer/Chrome/Linux-132.0.6834.83/chrome-linux64/chrome: error while loading shared libraries: libglib-2.0.so.0: cannot open shared object file: No such file or directory\n", "status": 500, "detail": " at PuppeteerSharp.States.ProcessStartingState.StartCoreAsync(LauncherBase p) in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/States/ProcessStartingState.cs:line 83\n at PuppeteerSharp.States.ProcessStartingState.StartCoreAsync(LauncherBase p) in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/States/ProcessStartingState.cs:line 89\n at PuppeteerSharp.Launcher.LaunchAsync(LaunchOptions options) in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/Launcher.cs:line 77\n at PuppeteerSharp.Launcher.LaunchAsync(LaunchOptions options) in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/Launcher.cs:line 110\n at API.Services.ExportService.GeneratePdfContent(String reportName, IViewModel model) in /app/src/API/Services/ExportService.cs:line 29\n at API.Controllers.ReportsController.TableReport() in /app/src/API/Controllers/ReportsController.cs:line 27\n at lambda_method1727(Closure, Object)" }
