HI all

We are currently facing the issue below with our 3 ASP.NET MVC projects created using the ABP boilerplate . Previously The projects were communicating with each other when making GET and POST requests when ran locally We then proceeded to deploy the ASP.NET solution to linux instances on AWS elastickbeanstalk and configured the endpoint to point to the deployed solutions URL's when making GET and POST requests from both deployed and localhost we are met with the error 500 message below is the detailed error retrieved from the log file

please advise

    On the other hand, ABP doesn't make a license check when you publish your project in Release mode. Please make sure it's on release mode.

    Also set your environment to Production/Staging (anything else rather than Development)

        ASPNETCORE_ENVIRONMENT = Development
