Is it possible to consume output from this library with openui5?

[mgerzabek]

I was stumbling over this library when looking on how to integrate a small demo of an openui5 app without a SAP backend. After setting up CORS it was easy to expose the $metadata file and access the catalogues defined in AppProvider.

But when I want to access entitysets in ui5 I get the message »Unsupported OData version 4.01«

Log.js?eval:499 2024-01-12 13:27:25.467800 Failed to get contexts for http://localhost/odata/Times with start index 0 and length 500 - Error: http://localhost/odata/$metadata: Unsupported OData version 4.01

    at convertXMLMetadata (http://localhost:8080/resources/sap/ui/model/odata/v4/lib/_MetadataRequestor.js:77:24) sap.ui.model.odata.v4.ODataListBinding

This brings me to my initial stated question: Is it possible to consume output from this library with openui5?

If yes, any hints are welcomed.
Thanks

Hi @mgerzabek, based on the error I'm going to guess the openui5 library supports OData 4.0, but not 4.01, and isn't sending the OData-Version header to indicate what versions it supports.

If you publish the lodata.php configuration you can edit the default version to 4.0 instead of 4.01 which is used if the client doesn't send a version.

Does that help?

Thank you @27pchrisl that worked!
