Thanks @niemyjski. Any chance you can also share the code that creates this index? Would be a lot easier for me to setup a repro.

[niemyjski]

Sure all the code can be found here: https://github.com/exceptionless/Exceptionless/tree/remove-mongo/Source/Core/Repositories/Configuration. Speficially all of the code for this is inside of the /indexes/eventindex.cs file.

Your custom analyzers are missing the type property, which causes our custom converter to blow up during deserialization.

Adding type = "custom" to all of the analyzers should fix the problem:

                analyzer = new
                {
                    comma_whitespace = new
                    {
                        type = "pattern",
                        pattern = @"[,\s]+"
                    },
                    email = new
                    {
                        type = "custom",
                        tokenizer = "keyword",
                        filter = new[] {
                            "email",
                            "lowercase",
                            "unique"
                        }
                    },
                    version_index = new
                    {
                        type = "custom",
                        tokenizer = "whitespace",
                        filter = new[] {
                            "version_pad1",
                            "version_pad2",
                            "version_pad3",

                    },
                    version_search = new
                    {
                        type = "custom",
                        tokenizer = "whitespace",

                        }
                    },
                    whitespace_lower = new
                    {
                        type = "custom",
                        tokenizer = "whitespace",
                        filter = new[] { "lowercase" }
                    },
                    typename = new
                    {
                        type = "custom",

                            "stop",
                            "unique"
                        }
                    }
                }

[niemyjski]

This seems like a bug... The serializer should handle this and automatically set it to custom if it's not defined. Or blow up when you try and insert it... If it's valid on the elastic search side, it shouldn't blow up trying to get settings.

[niemyjski]

Thanks for your help! I've added the type to our stuff. But I still think this should be fixed, just so others don't run into this.

[gmarz]

Actually, I wasn't aware that excluding the type is valid. ES allows you to create the analyzer on the index without a type, but does it actually apply it? If that's indeed the case, then you're right, this should be fixed.

[niemyjski]

Yes, we've been using this code for months and it's been working :). I got that json from elastic search.. It wasn't until I added a unit test for our reindexing that I ran into this issue :)
