swagger .net core API ambiguous HTTP Action debugging

Question

Implementing Swashbuckle/Swagger with .net Core 2 API I am now receiving the 500 error when accessing swagger.json:

NotSupportedException: Ambiguous HTTP

Answer 1

I solved this error by decorating the method mentioned in the error with the correct HTTP attribute. For exemple: [HttpGet]

This code throws error:

public object Get()
{
    MongoDbContext dbContext = new MongoDbContext();
    return new {
        API = true,
        Database = dbContext.Status()
    };
}

This code works:

[HttpGet]
public object Get()
{
    MongoDbContext dbContext = new MongoDbContext();
    return new {
        API = true,
        Database = dbContext.Status()
    };
}
