Question
Why does a REST POST call made to the STOP workflow Node returns with "system#invalidfetch" error and statusCode 400?
Steps followed to get this error are as follows:
STEPS TO REPRODUCE:
(A) Pre-reqs: Prepare a workflow, then validate, enable, and activate it.
-Process Name: SR_WFLOW12; Object: SR; Save; Notice, 1 Start and 1 Stop node is already present
-Drag 1 Condition node; 1 Stop Node; 2 Task Nodes; 2 Input Nodes; 2 Interaction Nodes to the workflow designer canvas
-Process Name: SR_WFLOW12; Object: SR; Save; Notice, 1 Start and 1 Stop node is already present
-Drag 1 Condition node; 1 Stop Node; 2 Task Nodes; 2 Input Nodes; 2 Interaction Nodes to the workflow designer canvas
-Perform following actions on each node:
1) START NODE
-Positive Line to a Condition
-Positive Line to a Condition
2) Condition Node
-Title-> REPORTED BY PRIORITY =4; Description-> REPORTED BY PRIORITY =4
-Expression-> :reportedpriority=4
-Positive Line to Task->TASK 5
-Negative Line to STOP1
-Title-> REPORTED BY PRIORITY =4; Description-> REPORTED BY PRIORITY =4
-Expression-> :reportedpriority=4
-Positive Line to Task->TASK 5
-Negative Line to STOP1
3) STOPNODE
-Title->STOP1
-Title->STOP1
4) Task Node
-Title-> TASK 5; Description-> TASK 5
-Application-> SR
-Under Assignments-> RoleID-> ORIGINATOR
-Perform Accept Action-> When any assignment is accepted
-Positive Line to Task->INPUT 7
-Negative Line to INTERACTION 9
-Title-> TASK 5; Description-> TASK 5
-Application-> SR
-Under Assignments-> RoleID-> ORIGINATOR
-Perform Accept Action-> When any assignment is accepted
-Positive Line to Task->INPUT 7
-Negative Line to INTERACTION 9
5) Input Node
-Title-> INPUT 7; Description-> INPUT 7
-Positive Line to INPUT 8
-Positive Line to INTERACTION 9
-Title-> INPUT 7; Description-> INPUT 7
-Positive Line to INPUT 8
-Positive Line to INTERACTION 9
6) Interaction Node
-Title-> INTERACTION 9
-Directions Title-> Primary interaction; Directions Body: Primary interaction
-Positive Line to INTERACTION 10
7) Interaction Node
-Title-> INTERACTION 10
-Directions Title-> Secondary interaction; Directions Body: Secondary interaction
-Positive Line to Task Node-TASK 6
8) Input Node
-Title-> INPUT 8; Description-> INPUT 8
-Positive Line to Task Node-TASK 6
-Positive Line to Stop Node - STOP2
-Title-> INPUT 8; Description-> INPUT 8
-Positive Line to Task Node-TASK 6
-Positive Line to Stop Node - STOP2
9) Task Node
-Title-> TASK 6; Description-> TASK 6
-Application-> SR
-Under Assignments-> RoleID-> ORIGINATOR
-Perform Accept Action-> When any assignment is accepted
-Positive Line to Stop Node - STOP2
10) From More Actions; Add workflow to Application: SR
11) Create a Service Request; TEST1; Priority: 4; Take Ownership; Route the workflow to the TASK 5 node
(B) Perform REST Queries to see the issue.
(1) Make a REST GET Request
GET URL
http://localhost:9080/maximo/oslc/os/mxapiwfassignment?_lid=maxadmin&_lpwd=maxadmin&oslc.select=*&lean=1&oslc.where=ownertable="SR"&oslc.where=owner="maxadmin"RESPONSE
Observe the workflow is at the TASK 5 node and it shows in the response 1 positive line to INPUT 7 Node and 1 negative line to INTERACTION 9 Node along with href link{
