trigger tDie for ERROR_MESSAGE in tRest

Anonymous — Tue, 03 Oct 2017 20:02:47 GMT

Could you guys help me understand how do I abort my job when tRest return an error. I tried doing Run IF -->tDie directly from tRest

((String)globalMap.get("tREST_1_ERROR_MESSAGE")).length() >0

but that results in NPE

Error on line 1 of document  : Premature end of file. Nested exception: Premature end of file.
Exception in component tREST_1
java.lang.NullPointerException

So now I'm using tMap to separate Body from ERROR_MESSAGE. I can't figure out what to do with error row though. I can't use "Run If" trigger directly with tMap:

What is the typical way of handling error from REST call?

Thanks,

Dima

There's a few ways to do what you want. The reason you're getting a NPE is because Talend will evaluate the "if" links when the component they are attached to runs their "end" section -- since the subjob with your tREST component has not even initialized at this point, the globalMap key will not be populated and the get will return null.

Here's a quick example of two ways to do what you want:

1) use onSubJobError off the tREST subjob

2) use a stub component to ensure the tREST subjob is complete before evaluating your if statement

I tried doing a OnSubjobError but tDie is not triggered. I can catch ERROR_CODE though

Here's my tMap just in case

I tried using another approach suggested with tJava component but it fails with error:

tJava_1 null

I'm having the same issue. Is there a solution for this?
