What's Wrong?

The error TypeError: undefined is not an object (evaluating 'Object.keys(b)') means:

• The /insights command tries to iterate over an object using Object.keys(b)
• But b is undefined — the data it expects doesn't exist
• Object.keys(b) in the minified code is the variable name after bundling/minification

Likely cause: The /insights command expects some data (probably conversation history, usage stats, or cached metrics) to be
present, but it's either:

1. Not initialized yet (e.g., first time running, no prior data)
2. The data format changed in an update and the code doesn't handle the missing/changed shape
3. A missing null check — the code doesn't guard against the data being undefined

It's essentially a missing null/undefined guard in the insights feature's code.

What Should Happen?

run /insights comnad
