I’m having an issue accessing one of my interfaces. It keeps on showing error 500 | Uh oh, something went wrong. `Unexpected token '<', "<!DOCTYPE "... is not valid JSON`.
Though I have no issue accessing my other interfaces.

New error showed up when I tried accessing it again (500 | Uh oh, something went wrong. JSON.parse: unexpected character at line 1 column 1 of the JSON data)

Hi there
Welcome to the Community! 🎉
Due to our limited resources regarding Interfaces. I’d recommend reaching out to our Interfaces Support Team regarding this issue.
You can reach our Interfaces team here: https://eap.zapier.app/interfaces
Hopefully, this helps.
Dear
It seems you might either be making the API call to the wrong route, or perhaps your configurations are not quite right, causing this kind of error:
**"Error 500 | Uh oh, something went wrong. `Unexpected token '<', "<!DOCTYPE "... is not valid JSON`.**"
I’d suggest using PostMan to debug the API call in an isolated environment.
Here’s a quick guide:
- Setting Up Postman:
- Ensure Postman is installed and set up correctly on your system.
- Create a new environment in Postman. (This will help you manage your secret keys variables. )
- Create a new request in Postman to the interface causing the error.
- Replicating the Issue:
- Input the URL of the problematic interface.
- Set the appropriate HTTP method (GET, POST, etc.).
- Add headers and body data if required.
- Analyzing the Response:
- Send the request and observe the response.
- Check if the response body contains HTML (indicated by `<!DOCTYPE`) instead of expected JSON format.
- Investigating the Error:
- If an HTML response is received, it often indicates a server-side error.
- The server might be misconfigured or encountering an internal issue.
- Comparing with Functional Interfaces:
- Send requests to the interfaces that are working correctly.
- Compare their request setup (headers, body, etc.) with the problematic one.
- Try different options like (form-data, raw, GraphQL, etc), depending on your configuration.
- Checking Server Logs:
- If possible, access the server logs to identify any internal server errors causing the 500 response.
- Consulting Server/Backend Team:
- If the issue persists, consult with your server or backend team with the details from Postman.
