installed pxpipe package does not export transformAnthropicM

Error message

installed pxpipe package does not export transformAnthropicMessages

What it means

Thrown by doLoad when the installed pxpipe package was successfully imported via dynamic import but does not export a `transformAnthropicMessages` function. The loader validates the module's API surface immediately after import and refuses to cache/use a module that doesn't implement the expected transform contract, protecting the request pipeline from calling an undefined function.

Solutions

1. Check the installed package's entry (libraryEntry()) and confirm transformAnthropicMessages is a named export in its package.json main/exports target.
2. Reinstall/upgrade pxpipe to the version this app expects (use the Repair action, which bumps the ?v= cache-bust and reloads), then restart the pipeline load.
3. Pin a known-good pxpipe version instead of @latest so upstream renames can't break the contract.
4. If you control both sides, re-add/rename the export: module.exports.transformAnthropicMessages = transform... (or export function transformAnthropicMessages).
5. Clear PXPIPE_DIR and reinstall cleanly to rule out a corrupted/partial install resolving to the wrong entry.

Example fix

// before (pxpipe package entry)
export { transformAnthropicMessages as transform };
// after: keep the contract export name
export function transformAnthropicMessages({ body, model }) { /* ... */ }

const mod = await import(pathToFileURL(libraryEntry()).href);
if (typeof mod.transformAnthropicMessages !== "function") {
  throw new Error("installed pxpipe package does not export transformAnthropicMessages");
}

function exportsTransform(mod) {
  return !!mod && typeof mod.transformAnthropicMessages === "function";
}

try {
  const { module: mod } = await loadPxpipe();
  if (!exportsTransform(mod)) throw new Error("incompatible pxpipe build");
} catch (e) {
  if (e.message.includes("does not export transformAnthropicMessages")) {
    await repairPxpipe(); // reinstall matching version, bump cache-bust
  } else throw e;
}

When it happens

Trigger: A different or older/newer version of the pxpipe package is installed whose entry point no longer exports transformAnthropicMessages; a stale/renamed export upstream; the cache-busting URL (?v=<version>) resolved to a wrong file; a corrupted install where the entry resolved to an unexpected module.

Common situations: Upgrading pxpipe and the library got out of sync (package renamed the export); an old cached install predating the current API; npm installed a placeholder/renamed package with the same name; semver drift between the app expecting the export and the @latest package fetched during install.
