Variable: E_TOOL_DOWNSTREAM_ERROR
ts
const E_TOOL_DOWNSTREAM_ERROR: CreatedException<[]>;Defined in: lib/exceptions/runtime.ts:414
Thrown (as a rejection reason) when a @nhtio/adk!Tool's handler throws during execution.
Remarks
Not fatal — a downstream tool failure is a recoverable runtime condition. The tool call loop catches this error specifically to report the failure back to the model rather than crashing the pipeline.
