| Problem                                                        | What to do                                                                                                                                                                                       |
| :------------------------------------------------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| An upload stops, or a specification shows the **Error** status | Check that the file is a valid OpenAPI 3.x or Web Services Description Language (WSDL) file, then upload it again.                                                                               |
| You can't create a project                                     | Confirm that the responder has indexed specifications on the **API Specs** page.                                                                                                                 |
| You see no upload action                                       | Ask your Grand Central administrator for upload permission. See [Connector Studio permissions](/connector-studio/reference/permissions).                                                         |
| The AI suggestions are empty                                   | Set the target API type, **REST** or **SOAP**, on the project.                                                                                                                                   |
| You see the wrong organization after you sign in               | Use the organization switcher, or sign in to the correct installation. See [Work across installations](/connector-studio/work-across-installations).                                             |
| MCP authentication fails                                       | Generate a new token on the **MCP Setup** page, and confirm that your configuration sends the `X-Installation` header. See [Connect from your IDE with MCP](/connector-studio/connect-with-mcp). |
| A transformation preview is empty                              | Approve the parent operation and its property mappings. See [Transformations and generated code](/connector-studio/transformations).                                                             |
