BasePath was used in Swagger v2.0 It has been replaced by the servers array in OpenApi v3.0

In v5 you have to do this for using OpenApi v3.0:

var basePath = "/v1";
app.UseSwagger(c =>
    {
        c.RouteTemplate = "swagger/{documentName}/swagger.json";
        c.PreSerializeFilters.Add((swaggerDoc, httpReq) =>
        {
            swaggerDoc.Servers = new List { new OpenApiServer { Url = $"{httpReq.Scheme}://{httpReq.Host.Value}{basePath}" } };
        });
    });
