Ошибка сервиализации / десериализации

[SergeyA]

Добрый день.

У нас используется библиотека stimulsoft.reports.angular.netcore\2021.3.7
При разработке на тестовой среде все успешно работает, но когда код запускаем на проде, то получаем ошибки в тех местах, где происходит сериализация/десериализация в строку/из строки объекта отчета.

В чем может быть дело?

При создании отчета падает на методе:
Report.LoadFromString(reportTemplate);

При загрузке во вьювер на методе:
report.Report = stiReport.SaveDocumentToString();

Вот так выглядит ошибка при создании:

Здравствуйте,

Необходимо некоторое время для анализа, о результатах дадим знать.

Спасибо.

Здравствуйте,

Не получается воспроизвести проблему на наших тестовых проектах.
Пожалуйста, вышлите простой пример проекта, который воспроизводит проблему, для анализа.

Спасибо.

Добрался до логов прода и увидел, что вьювер ругается на то, что не хватает библиотеки libgdiplus в базовом образе.
Добавили в докер файл соответствующую библиотеку и все заработало!

Если кому-то вдруг потребуется, начало докер файла у нас теперь выглядит примерно так:

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

RUN apt-get update && apt-get install -y libgdiplus

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src

Здравствуйте,

Спасибо за информацию.
