ERR_PACKAGE_PATH_NOT_EXPORTED against @sap-cloud-sdk/connectivity@4.9.0 (deep import of connectivity/internal.js)

• My issue is a JS/TS related issue, not a Java related issue.
• My issue is not already reported or documented.

Describe the Bug

@sap-ai-sdk/ai-api deep-imports an internal subpath of @sap-cloud-sdk/connectivity with a .js extension:

// @sap-ai-sdk/ai-api/dist/utils/deployment-cache.js
import { Cache } from '@sap-cloud-sdk/connectivity/internal.js';

@sap-cloud-sdk/connectivity@4.9.0 (published 2026-08-24) introduced a restrictive exports map that exposes "./internal" but not "./internal.js". Since exports subpaths are matched exactly, the .js import no longer resolves and every app using the AI SDK crashes during startup:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './internal.js' is not
defined by "exports" in .../@sap-cloud-sdk/connectivity/package.json
imported from .../@sap-ai-sdk/ai-api/dist/utils/deployment-cache.js

Steps to Reproduce

1. Install @sap-ai-sdk/ai-api (any version, incl. 2.15.0) with @sap-cloud-sdk/connectivity@4.9.0.
2. Load any module that reaches deployment-cache.js.
3. Startup throws ERR_PACKAGE_PATH_NOT_EXPORTED.

Expected Behavior

The declared range (^4.8.0) should work across all permitted @sap-cloud-sdk/connectivity versions, including 4.9.0.

Hey @gbrfarkas,

Thank you for opening the issue. Please update to SAP Cloud SDK v4.9.1 which should resolve the issue.
