Class: CCIPFinalityNotAllowedError

Defined in: errors/specialized.ts:3705

Thrown when a receiver contract rejects the requested finality.

The receiver either does not support "safe" (FCR) finality, or requires a higher minimum confirmation depth than what was requested. Inspect context.requested and context.allowed for the exact mismatch.

Example

TypeScript

try {
  await chain.estimateReceiveExecution({ offRamp, message })
} catch (error) {
  if (error instanceof CCIPFinalityNotAllowedError) {
    console.log(
      `Receiver ${error.context.receiver} rejected finality`,
      `requested=${error.context.requested}`,
      `allowed=${JSON.stringify(error.context.allowed)}`,
    )
  }
}

Methods

toJSON()

toJSON(): Record<string, unknown>

Defined in: errors/CCIPError.ts:105

Serializes the error for logging.

Use this instead of JSON.stringify(error) directly, as Error properties are non-enumerable and would be lost.

Returns

Record<string, unknown>

An object containing all error properties

Inherited from

CCIPError.toJSON

from()

static from(error: unknown, code?: CCIPErrorCode): CCIPError

Defined in: errors/CCIPError.ts:89

Wraps an unknown caught value in a CCIPError.

Useful for normalizing errors in catch blocks.

Parameters

Parameter	Type	Description
error	unknown	The error to wrap
code?	CCIPErrorCode	Optional error code (defaults to 'UNKNOWN')

Returns

CCIPError

A CCIPError wrapping the original error

CCIPError.from

isCCIPError()

static isCCIPError(error: unknown): error is CCIPError

Defined in: errors/CCIPError.ts:73

Type guard for CCIPError.

Prefer this over instanceof to handle the dual package hazard when multiple versions of the SDK may be present.

Parameters

Parameter	Type	Description
error	unknown	The error to check

Returns

error is CCIPError

True if the error is a CCIPError instance
