[SageX3 on-prem RestAPI Integration - query contract schema]

Hello I am new and I am hopeful someone can help me here.

I have a Demo SageX3 with Sage running.

I am developing a connect to this environment. I will be using Rest API option.

Many specific requests work.

Here are a few examples what works:

http://10.0.3.137:8124/sdata/x3/erp/X3ERPV12_SEED/SORDER('SONZA0210001')?representation=SORDER.$details

http://x3server:8124/sdata/x3/erp/X3ERPV12_SEED/BPCUSTOMER?representation=BPCUSTOMER.$query&count=20

However, the first request my application needs to make is to read the schema and get all the objects. SDATA documentation (http://sage.github.io/SData-2.0/pages/core/0401/)  indicates it is possible by accessing this URL

http://10.0.3.137:8124/sdata/x3/erp/X3ERPV12_SEED/$schema

This request fails with BAD REQUEST error.

How can I fix it? Do I need to enable something in Sage to access this request?

I will be very much thankful. If there is another forum to post things like this I will be happy to repost.

Thank you

Nick
