Services from `https://services.odata.org/v4/odata/` respond with header `OData-Version:` `4.0;` instead of `4.0`

[boghyon]

1. Go to https://services.odata.org/v4/odata/
2. Click on any of the mentioned services. E.g. https://services.odata.org/Experimental/Northwind/Northwind.svc/
3. The service's response header OData-Version has the value 4.0; which contains unexpectedly a semicolon and thus causes issues in the client. It should be without the semicolon: 4.0.

Is the extra semicolon OData V4 compliant? If not, it should be removed.
TripPin on the other hand does not have the issue.

I am also facing the same issue. Is it working for you?

I am also facing the same issue

With which service? The ones listed in https://services.odata.org/v4/odata/?

@ralfhandl Is the OData-Version response header value 4.0; syntactically allowed? Because the additional semicolon breaks the client OData implementation.

[ralfhandl]

The OData ABNF does not allow a trailing semicolon, see https://github.com/oasis-tcs/odata-abnf/blob/d1b3373f73408d1dd177198057cc12940a30c6c8/abnf/odata-abnf-construction-rules.txt#L1077.

Is there any progress on this?

Hi, at this point in time, the response from the v4 service at https://services.odata.org/v4/odata/ is still broken; it still returns "4.0;" in the "Odata-Version" header.
Is there anyone that can fix this?

Hi, any updates on this? I'm also facing the same issue.

Note that Trippin is the recommended V4 service, as it is built with the latest maintained V4 libraries. The Experimental services are built with a somewhat hacked version of the older OData V3 libraries and are harder to make changes (which is why they are not advertised on the odata.org website.
