Class: BlobFetchError

Defined in: src/atproto/errors/repository-errors.ts:202

Error thrown when blob fetching fails.

Remarks​

This error indicates failure to fetch a blob (PDF, image, etc.) from a user's PDS. The blob may exist but be inaccessible, or may not exist.

Example​

try {
  const stream = await repository.getBlob(did, cid);
} catch (error) {
  if (error instanceof BlobFetchError) {
    logger.warn('Blob fetch failed', { cid: error.cid, reason: error.reason });
  }
}

Constructors​

new BlobFetchError()​

new BlobFetchError(message, did, cid, reason, cause?): BlobFetchError

Defined in: src/atproto/errors/repository-errors.ts:229

Creates a new BlobFetchError.

Parameters​

message​

string

Description of the fetch failure

did​

string

DID of the repository owner

cid​

string

CID of the blob

reason​

Specific reason for failure

"not_found" | "network_error" | "pds_error" | "too_large"

cause?​

Error

Original error (if chained)

Returns​

BlobFetchError

Overrides​

ChiveError.constructor

Properties​

cause?​

readonly optional cause: Error

Defined in: src/types/errors.ts:71

Original error that caused this error (if any).

Remarks​

Error chaining allows tracking the full error context through multiple layers of the application. Useful for debugging complex error scenarios.

Example​

try {
  await fetchData();
} catch (err) {
  throw new ValidationError('Failed to validate data', 'field', 'required', err as Error);
}

Inherited from​

ChiveError.cause

cid​

readonly cid: string

Defined in: src/atproto/errors/repository-errors.ts:208

CID of the blob that failed to fetch.

code​

readonly code: "BLOB_FETCH_ERROR" = 'BLOB_FETCH_ERROR'

Defined in: src/atproto/errors/repository-errors.ts:203

Machine-readable error code.

Remarks​

Error codes are unique identifiers for error types, enabling programmatic error handling (switch statements, error maps), error tracking in monitoring systems, and client-side error translation (i18n).

Overrides​

ChiveError.code

did​

readonly did: string

Defined in: src/atproto/errors/repository-errors.ts:213

DID of the repository owner.

message​

message: string

ChiveError.message

name​

name: string

Defined in: node_modules/.pnpm/typescript@5.5.4/node_modules/typescript/lib/lib.es5.d.ts:1076

ChiveError.name

reason​

readonly reason: "not_found" | "network_error" | "pds_error" | "too_large"

Defined in: src/atproto/errors/repository-errors.ts:218

Reason for fetch failure.

stack?​

optional stack: string

Defined in: node_modules/.pnpm/typescript@5.5.4/node_modules/typescript/lib/lib.es5.d.ts:1078

Inherited from​

ChiveError.stack

stackTraceLimit​

static stackTraceLimit: number

Defined in: node_modules/.pnpm/@types+node@24.10.1/node_modules/@types/node/globals.d.ts:68

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

ChiveError.stackTraceLimit

Methods​

captureStackTrace()​

static captureStackTrace(targetObject, constructorOpt?): void

Defined in: node_modules/.pnpm/@types+node@24.10.1/node_modules/@types/node/globals.d.ts:52

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();

Parameters​

targetObject​

object

constructorOpt?​

Returns​

void
