String Array as CustomProperty Not Properly Evaluated in .NET SDK

[adamjez]

I have encountered an issue where specifying a string array as a CustomProperty is not properly evaluated in the .NET SDK. However, the same configuration is correctly evaluated in both the Statsig dashboard Test Config and the Node.js SDK.

For example, here are the user properties I'm passing:

{
  "country": "EE",
  "custom": {
    "abtest": ["82=2", "703=1"]
  },
  "customIDs": {},
  "locale": "et_EE",
  "statsigEnvironment": {
    "tier": "development"
  }
}

In the Statisg, I have a Feature Gate with the criteria:

• CustomProperty abtest Contains any of 703=1.

This rule correctly meets the condition for the given user in both the Statsig dashboard Test Config and the Node.js SDK. However, in the .NET SDK, this condition does not seem to evaluate as expected.

Questions:

1. Does Statsig officially support string arrays as custom properties?
2. If yes, is there a specific way to use it in the .NET SDK?

Environment:

• Version: 1.29.0
• Platform: Windows, Linux

Thank you for your help!
