I have the same PRoblem on this line

presentation.Save(outputPath, Aspose.Slides.Export.SaveFormat.Pdf);

If I convert it with dotnet.exe publish -r linux-x64 -o ../linux-x64 -c Release --self-contained true -p:PublishSingleFile=true

I can run it on my windows and in wsl2 but not on linux
I have tried different systems and docker images.

The lateast try was on

FROM mcr.microsoft.com/dotnet/sdk:6.0
apt install nuget msbuild mono-xbuild ttf-mscorefonts-installer

I get always this message

terminate called after throwing an instance of ‘std::logic_error’
what(): basic_string::_M_construct null not valid
Aborted (core dumped)

@Tivian_XI,
Thank you for contacting support.

The issue has been planned to be fixed in Aspose.Slides for .NET 24.2. This release will be published in the second half of February.

With Aspose.Slides for .NET 23.10 (from the ZIP package), you can use the following Dockerfiles.

For Debian:

FROM mcr.microsoft.com/dotnet/sdk:6.0-bookworm-slim AS build

WORKDIR /source
COPY *.csproj .
RUN dotnet restore
COPY . .
RUN dotnet publish --no-restore -o /app

FROM mcr.microsoft.com/dotnet/runtime:6.0-bookworm-slim

RUN apt-get update && apt-get install -y \
 libfontconfig1 \
 libfreetype6

WORKDIR /app
COPY --from=build /app .

ENTRYPOINT ["./CrossPlatformApp"]

For Ubuntu:

FROM mcr.microsoft.com/dotnet/sdk:6.0-jammy AS build

WORKDIR /source
COPY *.csproj .
RUN dotnet restore
COPY . .
RUN dotnet publish --no-restore -o /app

FROM mcr.microsoft.com/dotnet/runtime:6.0-jammy

RUN apt-get update && apt-get install -y \
 libfontconfig1 \
 libfreetype6

WORKDIR /app
COPY --from=build /app .

ENTRYPOINT ["./CrossPlatformApp"]
