Summary

SentryAttribute currently only supports primitive attribute values.

Problem

There is no support for array values, which limits attribute expressiveness for SDK users.

Proposal

Add support for arrays in SentryAttribute so users can attach list-like metadata without flattening or stringifying manually.

Blocked

This is currently blocked by various points in the pipeline. If you send attribute arrays now they dont show up in Sentry
