Hello,
we had the same error and fixed it by deleting the OData-Services and reconfigure them again:
Transaction /IWFND/MAINT_SERVICE
Select service ZINTEROP, delete SICF-Nodes (left bottom side), delete systemalias (right bottom side) and (important!) click again on ZINTEROP and choos "delete service".
After that "add service", select your Systemalias, click "get services", choose /UI2/INTEROP and click "add selected services".
We also had to to this procedure for the service "ZTRANSPORT" and "ZPAGE_BUILDER_*"
Good Luck!
