Can't unambiguously select between fixed arity signatures error in nifi 1.16.3

Master Collaborator

Hello Experts,

 

I am trying to upgrade nifi from 1.12.1 version to 1.16.3.

I have a script 'ECMAScript' which was working fine in 1.12.1and now behaving different in 1.16.3.


Below is the portion of code giving error in 1.16 version when 'xyzId' is null.

But it just logs null as expected in 1.12 version
 

var xyzId = flowFile.getAttribute('xyzId');
log.info(xyzId);

 

Below is the error in 1.16 version when null value received for above line (log.info() line throws below error)

Any idea how to fix this? I want to avoid checking null values for logging also

 

Thanks

@hegdemahendra ,

 

This looks like a regression to me. Could you please open a bug Jira on https://issues.apache.org/jira/projects/NIFI/ to report this issue?

 

A workaround for this would be to change your code like below:

log.info(String(xyzId));

 

Cheers

André
