Hello. I am trying to use the QuestPDF library with docker container. If i try to send a request via Postman, the following exception was occured:

"The type initializer for 'SkiaSharp.SKAbstractManagedWStream' threw an exception."

Dockerfile FROM mcr.microsoft.com/dotnet/sdk:6.0-focal as build WORKDIR /src RUN apt-get update && apt-get install libfontconfig1 -y COPY . .

RUN dotnet restore "./DataExportService.csproj" RUN dotnet publish "./DataExportService.csproj" -c Release -o /app --no-restore

FROM mcr.microsoft.com/dotnet/aspnet:6.0-focal WORKDIR /app COPY --from=build /app ./ EXPOSE 5000

ENTRYPOINT ["dotnet", "DataExportService.dll"]

---

Is it possible to suppress this error and make the container work correctly? Thanks.

Hello again. I managed to solve the problem myself. Below you will find the updated Dockerfile.

FROM mcr.microsoft.com/dotnet/aspnet:6.0-focal AS base
WORKDIR /app
RUN apt-get update && apt-get install -y ttf-mscorefonts-installer fontconfig libc6 libc6-dev libgtk2.0-0 libnss3 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libdrm-common libgbm1 libasound2 libappindicator3-1 libxrender1 libfontconfig1 libxshmfence1
RUN chmod 777 .

FROM mcr.microsoft.com/dotnet/sdk:6.0-focal AS build
WORKDIR /src
COPY ["DataExportService.csproj", "DataExportService/"]
RUN dotnet restore "DataExportService/DataExportService.csproj"

WORKDIR "/src/DataExportService"
COPY . .
RUN dotnet build "DataExportService.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "DataExportService.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "DataExportService.dll"]

Additional info: Also you need to specify a supported font in the document page.DefaultTextStyle(x => x.FontFamily(Fonts.Arial));
