DeltaLink with DeltaToken fails

Posted on by TT999

The BC API v2 returns http/500, and content: "{"error":{"code":"Unknown","message":"Internal Server Error. (500) "}}", when using a deltalink, returned from a previous "odata.track-changes".
The original query:
api.businesscentral.dynamics.com/.../customers
with header:
request.Headers.Add("Prefer", "odata.track-changes");
returns the deltalink:
api.businesscentral.dynamics.com/.../customers

Which produces the http/500
HttpMethod GET, version "1.1"
ConfidentialClient authentication

Any ideas, anyone?

Hello,

If you don't get further responses to this issue, you may want to raise a support request to Microsoft support via your CSP / Partner.

Hi, maybe the entity you are using may not support delta tokens.

https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-connect-apps-delta#delta-support-limitations

Hope this helps.

Thanks.

Thank you for replying.

I may be wrong, but I am under the impression that the standard customers API allows delta tokens.

At least the property "ChangeTrackingAllowed" is true in page 30009 "APIV2 - Customers".

And the http/500 does not occur on the deltalink request. The delta link is returned, but fails when used.

In anyone else struggles with this:
I opened a support request against Microsoft. And they have "acknowledged the situation", and will create a hotfix.
Which will be deployed after "up to 6 weeks".

Thank you, I did just that.

And they will be releasing a fix.
