[github-actions]

Note

The pull request "refactor: Update SentryAttribute to use a generic array type" was created by @itaybre but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

📜 Description

Replaces the array attributes type with a generic array

💡 Motivation and Context

After reviewing the developer docs, I found out that array attributes now expect array as the type.
Related:

• Docs fix: Add example of array attribute to telemetry attributes sentry-docs#15994
• Change in Sentry Native fix: update array attribute types to general 'array' string sentry-native#1479
• Relay feat(eap): Add support for native scalar arrays relay#5394

💚 How did you test it?

For now only unit tests, array attributes are not visible in Sentry UI so only unit tests

📝 Checklist
