Fixing the Eco Webserver Swashbuckle errorLast updated: 02/24/19
With the latest Eco server 0.8.0.0 and higher (tested up to 0.8.0.3), you may find that your Eco server doesn't start the webserver up correctly, breaking a lot of essential in-game functionality. It turns out it's significantly more difficult to save the world without scientific data, laws, or a basic government (who would have known?). Without the global impact created from this UI, the game was effectively broke or unusable.
The error printed from the server during startup will look something like the following. There's a larger stacktrace that we've condensed for easier readability.
Failed to start webserver (TargetInvocationException): Exception has been thrown by the target of an invocation. ... Method not found: Swashbuckle.Application.SwaggerEnabledConfiguration Swashbuckle.Application.HttpConfigurationExtensions.EnableSwagger(System.Web.Http.HttpConfiguration,System.Action`1<Swashbuckle.Application.SwaggerDocsConfig>)
This error is common when running the server via Linux in a Mono environment. There have been reports of a similar error in Windows, but this fix has not been confirmed working there yet.
This error is a result of certain Windows specific libraries seemingly not being loaded, despite being required for the webserver.
