Errors encountered in setting up API Nodes

Hello,

My DSS instance is deployed on a regular GCP compute instance. I was trying to deploy an API for my predictive model, but I kept running into issues with the API nodes in the API Deployer Infrastructures. Is there any documentations on how to properly set up API nodes?

The error message shows "Expected a com.google.gson.JsonArray but was com.google.gson.JsonPrimitive". Wanted to see if I can get some help with setting up API nodes properly that works with GCP. Thanks!

Best,

Mark

    Hi,

    First of all, are your API nodes and API deployer running the same version of DSS ? Was the model that you are trying to deploy trained with the same version of DSS ?

    If there are no version mismatches, please open a support ticket as described in https://doc.dataiku.com/dss/latest/troubleshooting/obtaining-support.html

    In your support ticket, please include:

    • An instance diagnosis of your API deployer node. Go to Administration > Maintenance > Diagnostic tool and send us the resulting file. Note that you need to be administrator of the DSS instance - else you'll need to ask your admin.
      If the resulting file is too large for mail (> 15 MB), you can use https://dl.dataiku.com to send it to us. Please don't forget to send the link that is generated when you upload the file.
    • The "run/apimain.log" file from your API node
