Import external service odata v4 , Error : No metadata factory provided

[SamyD]

After generating my CAP project, I want to import and use external service odata (OP or Private Cloud). If I download an edmx odata v2 file from sap business hub api or from the AS, the command “cds import myedmx.edmx” works correctly.

However, if I take an edmx file from an odata v4 service from https://api.sap.com/api/OP_PRODUCT_0002/overview or https://api.sap.com/api/OP_PURCHASEORDER_0001/overview

or directly from AS

I got this error:

cds import ..\OP_PRODUCT_0002.edmx                 
Error: No metadata factory provided. Can not resolve 'com.sap.vocabularies.Common.v1'. Please add one via Strategy.setMetadataFactory(function(type, callback){})

If i try to delete tag "'com.sap.vocabularies.Common.v1'" in metadata, i have same error but in another tag.

Specs :

This is probably a recently introduced bug. Try importing using an earlier version. For example, this is not an issue in '@sap/cds-dk@8.2'.

```

npm add -D '@sap/cds-dk@8.2'

npm exec cds import  ~/Downloads/OP_PRODUCT_0002.edmx

```

Thanks Dinu it's good now 🙂

it's weird because it's working with command "npm exec cds import ..." but not with command "cds import ..."

Hi, how did you solve it? I'm trying to use this API in a CPI iFlow and it's not working. I got the error "invalid or missing namespace for schema".

same here. I'm using CAP JAVA. But the downgrade of dev dependencies didn't work for me. Maybe it has use my global cds-dk. .... So i switched it for a the import. npm add -g '@sap/cds-dk@7.3'  . Then import and after that switch back  npm add -g '@sap/cds-dk@8.6'
