# NousResearch/hermes-agent · Bug fix: dict-valued 'type' key crashes payload estimator

## Open now

- Nothing open on GitHub.

A TypeError was raised in the watchdog payload estimator when a tool JSON schema contained a property named 'type' with a dict value instead of a string. Two fix attempts address this by making the estimator tolerate such schema-valued keys.
