Class: CCIPRateLimitExceededError

Defined in: errors/specialized.ts:992

Thrown when TokenPool's rate limit is not enough for the requested amount. Transient: rate limit may refill after some time, or user can reduce amount and retry immediately. Not transient: amount exceeds total capacity of the pool, so it will never be processable until pool configs change.

Example

TypeScript

let fee
do {
  try {
    fee = await chain.getFee({
      router,
      destChainSelector,
      message: { receiver, tokenAmounts: [{ token, amount }] },
    })
  } catch (error) {
    if (!(error instanceof CCIPRateLimitExceededError) || !error.isTransient) {
      throw error
    }
    console.log(`Token ${error.context.token} exceeds rate limit, retrying after ${error.retryAfterMs}ms`)
    await sleep(error.retryAfterMs)
  }
} while (fee === undefined)

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
