[BUG] MCP - Self-Hosted - Zoho Projects

**Describe the bug**
After authenticating with the MCP server and obtaining an OAuth token, I attempted to request information about a Project and it gave me an error message.

```
{
"errors": [
"{\"code\":\"UserError\",\"message\":\"bad options response for prop: portalId\",\"ts\":\"2025-07-15T16:17:19.068Z\",\"cellId\":null,\"stack\":null,\"$debug\":null,\"name\":\"UserError\"}"
],

```

In the Hosted version it works.
To give more context, I am testing it on N8N workflow and the request I am sending with system prompt is the same for both Hosted and Self-Hosted.

**To Reproduce**
I gave the following prompt to my AI Agent: "Give me the name of the project manager for ...".

**Expected behavior**
The name of the project manager.

**Screenshots**
Here is what is being sent.

Here is what was sent on the Hosted one, which looks fine.
