Properties

code

readonly code: ErrorCode

Status code, a value from ErrorCode enum. It is directly mapped to HTTP, status, it is a constant value to be used by clients integrating with the chain.

Implementation of

OptionalChainErrorData.code

Source

chain-api/src/utils/error.ts:45

key

readonly key: Uppercase\<string>

An upper case string to be used as a key do diagnose where the error comes from and help with regular development. It should not be used by client integrating with the chain since we don't guarantee it won't change. It is generated from original error class name.

OptionalChainErrorData.key

Optional override for formatting stack traces

Methods

andExec()

andExec(fn): ChainError

Allows to execute function getting as a parameter the current error.

Parameters

▪ fn: (e) => void

Returns

Example

throw CommonChainError.objectNotFound(objectId).andExec((e) => {
  logger.error(e.message);
});

chain-api/src/utils/error.ts:114

logError()

logError(logger): ChainError

Parameters

▪ logger: object

▪ logger.error

Source

chain-api/src/utils/error.ts:119

logWarn()

logWarn(logger): ChainError

Parameters

▪ logger: object

▪ logger.warn

Source

chain-api/src/utils/error.ts:124

map()

map(key, newError): ChainError

Maps ChainError to another chain error by error code if key param matches current error code or current diagnostic key. Otherwise, returns original error.

Useful in rethrowing an error or mapping an error to another one in catch clauses or catch methods in promises.

Parameters

▪ key: ErrorCode | ClassConstructor\<ChainError>

error code or error class to match

▪ newError: ChainError | (e) => ChainError

new error or a function to create the new error

Source

chain-api/src/utils/error.ts:148

matches()

matches(key): boolean

Parameters

▪ key: ErrorCode | ClassConstructor\<ChainError>

Source

chain-api/src/utils/error.ts:129

captureStackTrace()

static captureStackTrace(targetObject, constructorOpt?): void

Create .stack property on a target object

Parameters

▪ targetObject: object

▪ constructorOpt?: Function

Inherited from

Error.captureStackTrace

Source

node_modules/@types/node/globals.d.ts:4

from()

static from(e): ChainError

Parameters

▪ e: object & object

Source

chain-api/src/utils/error.ts:168

isChainError()

static isChainError(e): e is ChainError

Parameters

▪ e: undefined | object

Source

chain-api/src/utils/error.ts:164

map()

static map(e, key, newError): ChainError

Maps ChainError to another chain error by error code, or returns original error if no error code matches, or returns default chain error if a given parameter is not a ChainError instance.

Useful in rethrowing an error or mapping an error to another one in catch clauses or catch methods in promises.

Parameters

▪ e: ChainError | object

original error

▪ key: ErrorCode | ClassConstructor\<ChainError>

error code or error class to match

▪ newError: ChainError | (e) => ChainError

new error or a function to create the new error
