Hi all,

I am trying to use https://github.com/unchase/Unchase.OData.Connectedservice/ to generate OData client C# code based on a metadata file. The service is hosted on SAP S/4HANA and the metadata is in version 2.0. Here is the content of the metadata:

The following steps show how I imported the metadata file:

As you can see on the last step I have received an error.

I also tried to import https://services.odata.org/V2/Northwind/Northwind.svc/$metadata file and it generated OData client without any error.

Best regards

I also have the same error

austalakov commented 1 year ago

Same error on a different SAP S/4HANA service. I hoped running through the odata-cli instead of the Visual Studio extension would give some more details but it fails silently.

henrikcrepido commented 1 year ago

Had the same issue but was resolved by downloading the schema and removing: <Annotation Term="Core.SchemaVersion" String="1.0.0" xmlns="http://docs.oasis-open.org/odata/ns/edm"/>

EricSch commented 10 months ago

Wow. same here and no answer yet from Microsoft

@henrikcrepido And it didn't help to remove this line

EricSch commented 9 months ago

I advise not use this tool, even not anything different from Microsoft. I opened an official support request at Microsoft. They didn't provide any help with this issue.

My conclusion:

  1. Don't use the OData Connector
  2. Don't use anything from Microsoft
