Troubleshooting Common Issues with CustomGPT.ai

A 401 Unauthorized error usually means your request did not send a valid API key in the format the API expects. In Postman, confirm the Authorization header is set to `Bearer `, use the correct endpoint, and set `Content-Type: application/json` when sending JSON. If it still fails, verify the request method matches the endpoint and check the Postman console or request logs for the exact server response.

Bernalillo County handled 114,836 contacts and reported a 4.81x ROI, showing that high-volume deployments can work reliably when requests are configured correctly. If responses are slow, first confirm the endpoint, HTTP method, headers, and JSON body are correct. Then use Postman logs to inspect the exact response and, if the request succeeds but Postman stops waiting, increase the timeout setting in Postman. If you are on a restricted network, firewall or proxy settings are also worth checking.

Invalid Input errors usually come from a malformed request body or incorrect headers. Make sure your body is valid JSON, use Postman’s JSON validation if needed, and set `Content-Type: application/json`. If your parser reports `Unexpected token `, inspect the raw response before parsing and recheck that you are calling the API endpoint with the expected JSON request format.

Barry Barresi described a working deployment this way: “Powered by my custom-built Theory of Change AIM GPT agent on the CustomGPT.ai platform. Rapidly Develop a Credible Theory of Change with AI-Augmented Collaboration.” If the same call works in Postman but fails in your app, compare the exact request your app sends with the successful Postman request. Because authentication is API-key based, verify the same Authorization header, endpoint, HTTP method, and JSON body are being sent in both places.

A “Model not available” error usually points to account access restrictions, an incorrect model ID, an invalid API key, or a usage limit being reached. In Google Colab, recheck the model ID in your code, confirm the API key is valid and loaded correctly, and make sure the model is available to your account. If you recently changed credentials, restart the runtime and retry with the corrected values.

Michael Juul Rugaard of The Tokenizer said, “Based on our huge database, which we have built up over the past three years, and in close cooperation with CustomGPT, we have launched this amazing regulatory service, which both law firms and a wide range of industry professionals in our space will benefit greatly from.” When answers are inaccurate after you upload files or index a site, check the source before rewriting prompts: confirm the file type is supported, each file is under the 100MB limit, the specific document or URL was actually ingested, and the answer exists in that source. Because the system is RAG-powered with citation support, citations can help you verify whether the right source content was retrieved.

The platform supports 1,400+ integrations via Zapier. If a webhook or CRM integration is creating duplicate or missing records, first reproduce the same action with a direct API request in Postman. If the direct call works, compare the integration’s endpoint, HTTP method, Authorization header, `Content-Type`, and JSON body with the working request so you can see whether the integration is sending the wrong payload or repeating the call.
