It is recommended to throw a more detailed error message here
I debug the source code , here the clue is broken.

NJsonSchema/src/NJsonSchema/JsonPathUtilities.cs

Line 71 in 80c5d00

throw new InvalidOperationException("Could not find the JSON path of a referenced schema: " +

How do I output the error information here?

          if (mappings.Any(p => p.Value == null))
            {
                var errorItems = mappings.Where(p => p.Value == null).Select(x => x.Key.GetType().FullName);
                throw new InvalidOperationException("Could not find the JSON path of a referenced schema: " +
                                                     string.Join(",", errorItems) +
                                                    ",Manually referenced schemas must be added to the " +
                                                    "'Definitions' of a parent schema.");
            }

I'm getting this error in nswag and I have no way to diagnose what the problem is as a result of this error message.

I'm also seeing this. When I look at which one is missing a value, it appears to be a JsonSchema object with no values at all, but I can't see where it's coming from:

Looks like it's trying to resolve the schema for a JValue property but getting null as a reference and then throwing this error

It might be possible to add some custom filters to locate the problem in the following way

            services.AddSwaggerGen(options =>
            {
                options.UseInlineDefinitionsForEnums();
                options.DocumentFilter<SwaggerDocumentFilter>();
                options.CustomSchemaIds(type => type.Name);
                options.SchemaFilter<SwaggerEnumSchemaFilter>();
                options.OperationFilter<SwaggerOperationIdFilter>();
                options.OperationFilter<SwaggerOperationFilter>();
                options.ParameterFilter<SwaggerEnumParameterFilter>();
                options.CustomDefaultSchemaIdSelector();
...
