toError

toError(value): Error

Defined in: packages/protocol/src/lib/to-error.ts:20

Coerce an unknown thrown value into an Error instance.

try { ... } catch (e) { ... } typically yields e: unknown. Most error- handling sites need an Error instance to attach as cause, log a stack, or propagate through APIs that require Error. This helper preserves the original Error if one was thrown, and otherwise wraps the stringified value in a new Error so the call site never has to branch.

Parameters

value

unknown

Returns

Error

Example

try {
  await risky();
} catch (err) {
  logger.error('risky failed', toError(err));
}
