Have you tried to export it from 2014 and import it into 2018 instance using ^SECURITY command?

I used it with no problem for this application:

The error message talks about a restriction for unauthorized access to %Api.Atelier class, maybe that class override the /login?

I was Java developer for more than 15 years and for me to use arguments by reference was totally disgusting, you can use it in Java, but it's not very common, in Objectscript is the opposite, Output arguments are the rule, no the exception.

Calling instance methods using variables not declared as arguments made me feel dirty.

Is the ID that you are using the same that was generated by the server? 

Long life to @Robert Cemper !

PUT and DELETE works, but you have to use as id the generated by FHIR server, you can't use MRN or any other type of id.

Sales engineers are the best!

Congratulations to the winners!

Sorry for the delay, at the end of your third point your request is a HS.FHIRServer.Interop.Request object, this object has a property called RequestMethod in which you define the method (PUT, POST, DELETE). Define it to PUT and it should work (if your resource has the id assigned by the FHIR server before).

Hi! You have to define in the HS.FHIRServer.Interop.Request message the property RequestMethod. Take a look to this article.

You have to include the non-mirrored database from the primary instance of the mirror.
