API Builder in DX cloud returning a 500 error?

Hi There

I am using DX Cloud and have installed the API Builder plugin.

I have created a simple API and when accessing via the API Builder's OAS3 Document page, I get a 200 response containing the correct JSON result.

However when accessing the the API directly via Postman, DX Cloud is returning a 500 error response.

There seems to be nothing in reported either the application or system logs.


Does the DX Cloud support the API Builder, and if so what can I do to get around the 500 error?


Cheers

Dave

      Hi Anders

      Yes I have an API key configured via the Manage API Key Menu.

      The 500 error seems to occur regardless of whether you do a simple GET request or a POST request with the api_id and api_key included in the header.

      Should a simple GET request generate a 401 or 403 error if no key is specified rather than a 500?

        Hi Anders

        Whilst the 500 error is reproducible by viewing the following in a browser: https://kiwicivil.cloud.joget.com/jw/api/list/equipmentList

        Doing this does not generate an error in either the Web App Log or the System Log.

        However there looks to be a related error in the Web App Log from yesterday, possibly from when I installed the API plugin?

          It seems like you may be missing the API key. Did you add a Manage API Key Menu into your app to manage API keys?

        Hi Anders

        Thanks for your response.

        I checked both the web app log viewer as well as the System log viewer, and neither had a record of the 500 error.

          Hi, if there is a 500 error response, the exception should be logged. Did you check the Web App Log Viewer?
