In your app
A function makes the call on the client it is given, so your code passes the real one and a test passes a fake.Add the function
src/attract/revert-image-published-to-previous.ts
Call it
A script makes the client once and calls the function:A route handler, a job or a queue worker calls it the same way.
scripts/revert-image-published-to-previous.ts
Terminal
invalid when there is none.
Find the id
id is the document’s _id, from a list. Ask the list for only the fields you need: each row is a document’s id and those fields.
TypeScript
row.id as id. Drafts: list with { aposMode: 'draft' } to get the draft’s id (Find an id).

Returns
An
Image. Built-in image/media piece type for managing photos and graphics. Read its properties (image.id): each says whether the site always sends it. The example answer is the site’s wire JSON: some keys differ from the property names (_id → id, _tags → tags, _folder → folder …).Always sent. Who may see it on the site:
public (everyone) or loginRequired (signed-in people only). One of public, loginRequired; a newer site may send others, so keep a fallback.Sometimes sent:
undefined when the site leaves it out, and it can be null. In the archive: kept, but out of every list and off the site until it is restored. false (or null) for a live document.Sometimes sent:
undefined when the site leaves it out, and it can be null. Image credit or attribution.Sometimes sent:
undefined when the site leaves it out, and it can be null. The _id of the piece/page that was copied to create this document (only present if created via _copyingId)Sometimes sent:
undefined when the site leaves it out, and it can be null. Image description used for accessibility.Sometimes sent:
undefined when the site leaves it out, and it can be null. Its tags, as documents.Sometimes sent:
undefined when the site leaves it out, and it can be null. When set, a URL; empty or null when not.Sometimes sent:
undefined when the site leaves it out, and it can be null. The media folder holding it (one at most; empty at the library’s root).Sometimes sent:
undefined when the site leaves it out, and it can be null. The draft’s preview share key, while its share link is on: the link is the draft’s _url with aposShareKey and aposShareId (the draft’s _id) in its query. Absent otherwise, and on published documents.Errors
Errors
Nothing to catch: the SDK retries what is safe, and throws the rest as the classes below; catch only what you want to react to (see Errors and testing).
The site refused what was sent:
errors lists each field’s problem, siteMessage the first.Retried first: No. Read: errors (field → messages), siteMessage.The API key is missing or refused (malformed, revoked, expired), or a signature its signing mode needs is missing or stale.Retried first: No. Read:
siteMessage, errorName, data.The key may not do this: a scope it lacks, or an address outside its allowlist.
siteMessage names it.Retried first: No. Read: siteMessage, errorName, data.Nothing matches, or the caller may not see it.Retried first: No. Read:
siteMessage, errorName, data.The site failed. Its logs say why.Retried first: No: a write may have landed. Read:
siteMessage, errorName, data.No answer: DNS, a refused connection, TLS, or the timeout (15 s per attempt by default).Retried first: Only when nothing reached the site (
neverConnected()); never after a timeout, when it may have landed. Read: reason, neverConnected.The client refused to send it (e.g. a path segment of
..); the site never saw it.Retried first: No. Read: reason (what to change).Any other status, or a success whose JSON doesn’t match this SDK version’s types (update the SDK).Retried first: No. Read:
reason, status.sites.forSite('acme') named a slug your sites (createSiteClients()) don’t have.Retried first: No: nothing was sent. Read: message, slug.Behavior
- Access: an API key with
content:images:write(or a master above it:content:images:all,content:all,admin:all). A signed-in person may call it as far as their own permissions allow; anyone else gets 403. - Rate limit: the key’s own writes-per-minute limit, set when the key is created (default 120); over it, 429 with
Retry-After. The client waits and retries for you; you seeRateLimitedonly if that runs out. - Retries: a write is sent again only after a 429 (refused before it acted) or when it never reached the site. After a timeout or a 5xx it may have landed: check before you send it again.
- Timeout: 15 s per attempt by default; raise
timeout(milliseconds) on the client for longer.
Test it
It calls the function above with a fake client: the fake answers every call with a valid example, so nothing leaves your machine and no settings or key are needed. Run it withnode --test.
tests/media-revertImagePublishedToPrevious.test.ts
media.revertImagePublishedToPrevious with factories.Image({...}), the fields you give over a valid example (nested ones too).
