Dictionary exception in BucketsPathConverter

[gpetrou]

Elastic.Clients.Elasticsearch version: 8.13.5

Elasticsearch version: 8.11

.NET runtime version: 8.0

Operating system version:

Description of the problem including expected versus actual behavior:
Check

elasticsearch-net/src/Elastic.Clients.Elasticsearch/_Generated/Types/Aggregations/BucketsPath.g.cs

Line 120 in 00c8b42

_uniquePropertyToType = new Dictionary<string, Type> { { "", typeof(string) }, { "", typeof(IReadOnlyCollection<string>) }, { "", typeof(IReadOnlyDictionary<string, string>) } };

.
It tries to use multiple empty keys and this will eventually lead to Dictionary exceptions when attempting to use the buckets path functionality.
This makes it impossible to use BucketSelectorAggregation.

Hi @gpetrou, thanks again for reporting.

This looks like a bad one. I'll look at it later today.

It seems like I have to hand-craft the converter for this type as it's an union of string | string[] | Dictionary<string, string> and/or potentially improve the MultiItemUnionConverter<TUnion, TEnum> type to be able to handle these unions that contain multiple different datatypes.

@flobernd any updates on this?

Hi @gpetrou, not yet. The plan is to hand-craft this union. I expect to include a fix for this in the next few days. Maybe even today, but I can't promise anything 😋

Fixed in 8.13.10
