Error setup MCP server

Bug Report
1

I followed the documentation and configured the MCP server on Google Antitygravity as follows:

"API Documentation": {
  "command": "npx",
  "args": [
    "-y",
    "apidog-mcp-server@latest",
    "--project-id=<correct id>"
  ],
  "env": {
    "APIDOG_ACCESS_TOKEN": "<correct token>"
  }
}

However, it throws the following error:

Error: calling "initialize": invalid character 'A' looking for beginning of value.

Thanks for your feedback. We’ll try to reproduce this issue locally.
