Need help in running ASP.NET Core Web API in Docker Container

I am new to Docker. I have installed DockerDesktop. I am trying to expose an ASP.NET Core Web API via docker containers.

This is my docker file:

# This stage is used to build the service project
FROM *****/dotnet-80-sdk-runtime:latest AS builder #local artificatory within my company
ARG BUILD_CONFIGURATION=Release
WORKDIR /build
USER root
COPY ./NuGet.Config ./NuGet.Config 
COPY . .
RUN ls -la
RUN dotnet restore "./GrafProm.API.csproj" --configfile ./NuGet.Config
RUN dotnet build "./GrafProm.API.csproj" -c Release --no-restore -o /app/buildOutput
RUN dotnet publish "./GrafProm.API.csproj" -c Release --no-restore -o /app/publish

FROM *****/dotnet-80-runtime:latest AS run
EXPOSE 8080
ENV ASPNETCORE_URLS=http://+:8080
ENV DOTNET_ROOT=/usr/mware/dotnet
ENV ASPNETCORE_ENVIRONMENT=development
USER root
RUN mkdir -p /var/log/containers
#
WORKDIR /app
COPY --from=builder /app/publish .
ENTRYPOINT ["dotnet", "GrafProm.API.dll"]

I am using VS 2022 and this is my launchsettings.json file:

 "profiles": {
    "http": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": true,
      "applicationUrl": "http://localhost:5293"
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "Container (Dockerfile)": {
      "commandName": "Docker",
      "launchBrowser": true,
      "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}/swagger",
      "environmentVariables": {
        "ASPNETCORE_HTTP_PORTS": "8080"
      },
      "publishAllPorts": true,
      "useSSL": false
    }

When I run the container (Dockerfile) in VS, the image and container are getting created, but I get this error:

Instead of getting swagger page, I am getting an error page in IE.

Can someone help?

Thanks in advance.
