Nullpointer exception when using variable in tRestClient

[Anonymous]

Hello Talend Community

I am attempting the following. 

Read from database, create variable, use variable in a REST service parameter for execution. 

Attached is my job details and error.

When I change the variable from ((String)globalMap.get("row2.address")) to static "1", everything works fine

Job Steps:

tMysqlInput--(Main)->tFlowToIterate--(Iterate)--->tFixedFlowInput--(Main)-->TRESTClient--->tLogRow

I have looked at this thread (https://www.talendforge.org/forum/viewtopic.php?pid=140765#p140765) but the steps also leads to the same resultJob

Hi,

With tFlowToIterate, the default name from global variables is based on input flow, not output flow.

So, replace "row2.address" by "row1.address" and try again.
