BPMS 6.2 server REST API partial failures due to SQL error
I am only able to get some of the documented REST API for the BPM server working. For example, the following call works as expected:
http://<serverdomain>:8080/business-central/rest/query/runtime/process?pid=TestProject2.SeqTaskFlow
and it returns process instances associated with the given process ID. Likewise, the call:
http://<serverdomain>:8080/business-central/rest/organizationalunits/
returns a list of available organizational units.
However, many data retrieval calls do not work. (I haven't even tried yet to manipulate processes and tasks through the API.) In fact, all task-related calls seem to be failing. For example:
http://<serverdomain>:8080/business-central/rest/query/runtime/task?pid=TestProject2.SeqTaskFlow (same as above process call but retrieving task info instead)
return as 500 status because of server errors (appended below). I've tried many variations of query parameters, no parameters, etc. and get the same results, regardless of whether there are no active process instances, there is an active process instance but no claimed tasks, or there are both claimed/completed and unclaimed tasks. There is a problem with SQL trying to access an unknown "ORGANIZATI2_.ID" column. Does anyone know what the problem is or how to resolve it?
