Не получается генерировать pdf при помощи libwkhtmltox в docker контейнере

Не получается генерировать pdf при помощи libwkhtmltox в docker контейнере. На IIS Express все работает. При создании контейнера библиотеки копируются, в самом контейнере они есть, проверял. Лежат в папке app/PdfGenerationLib/64/libwkhtmltox.

Вот мой docker файл:

FROM mcr.microsoft.com/dotnet/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 9090

FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
WORKDIR /src
COPY ["CoreAPI/CoreAPI.csproj", "CoreAPI/"]
COPY ["DAL/DAL.csproj", "DAL/"]
COPY ["Infrastructure/Infrastructure.csproj", "Infrastructure/"]
COPY ["BL.Services/BL.csproj", "BL.Services/"]
COPY ["DTO/DTL.csproj", "DTO/"]
RUN dotnet restore "CoreAPI/CoreAPI.csproj"
COPY . .
WORKDIR "/src/CoreAPI"
RUN dotnet build "CoreAPI.csproj" -c Release -o /app/build

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

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

Вот файл docker-compose:

version: '3.4'

services:
  coreapi:
    image: image_timetable_api 
    container_name: container_timetable_api
    build:
      context: .

В браузере получаю такую ошибку.

Сам метод который генерит pdf:
