Missing or invalid '{key}' parameter

Error message

Missing or invalid '{key}' parameter

What it means

Generic guard in read_required_i64 for computer-use actions: the named integer parameter ({key}, e.g. coordinate or key-code fields) is absent from params or not representable as i64. Validation of the action's numeric arguments fails before dispatch to the endpoint.

Solutions

1. Include {key} as an integer in the action params
2. Ensure the value is a JSON number, not a string
3. Keep coordinates within configured limits
