this._reportError is not a function

_reportError function is called in kcl_manager but it is not defined

https://github.com/awslabs/amazon-kinesis-client-nodejs/blob/4790a36223954f487f71b0f8b67040a017304729/lib/kcl/kcl_manager.js#L67

Start by reading lib/kcl/kcl_manager.js at the linked line and trace the call to _reportError in the manager entry point. Reproduce the reported TypeError if possible and inspect nearby error-handling behavior. Done means the reported call no longer fails because _reportError is undefined, with the existing behavior preserved.
