[ACTION] unable to create image and text posts

**Describe the bug**
I am unable to post images to LinkedIn via the Pipedream MCP server. I receive an authorization error (403 Forbidden) indicating that the authenticated user ID is missing or invalid.

**To Reproduce**
Steps to reproduce the behavior:

1. Connect your LinkedIn account to the MCP server using Pipedream.
2. Attempt to create a LinkedIn post through the Pipedream MCP server.
3. Observe the authorization error: "The authenticated user ID is missing or invalid, resulting in an authorization error (403 Forbidden) from LinkedIn."
4. See the reproduction on Pipedream chat at: `https://chat.pipedream.com/chat/9498e4ca-e957-430a-97ff-9bef8c74ab38`

**Expected behavior**
I expect to be able to successfully post to LinkedIn through the Pipedream MCP server after authenticating my LinkedIn account. The image post should be created without any authorization errors.

**Additional context**
The error suggests a problem with authentication or authorization when trying to post on my behalf, despite a successful connection of the LinkedIn account to the MCP server. Possible reasons include:
* **Token Scope or Expiry:** The access token from Pipedream/MCP might lack correct permissions for image posting or may have expired.
* **MCP Server Integration:** The MCP server might not be correctly passing the LinkedIn user ID or access token to the LinkedIn API, or there might be a mismatch between the Pipedream authenticated session and the IDE context.
* **User Context:** The integration might require explicit user context (user ID/profile) to be passed with each request, which might be missing.
* **Pipedream vs. IDE Context:** The authentication from Pipedream may not be valid in the IDE or MCP server context if tokens are not shared or valid for both environments.
