Script Runner Error 'Failed type checking'

[Francisco Trindade]

I am trying to use script runner to be able to check my scripts for any error/deprecated classes. However for two files simply says that there was an error:

Failed type checking and we don't know why, it's our fault not yours @ line 1, column 1.

Is there any possible reason why the it is doing this. I know for a fact there should be some errors indicating deprecated classes since there are a few calls to component manager in there.

UPDATE: Found the following piece of code that is causing the error

Map tmprc = issue.getCustomFieldValue(rcObj) as Map
 if (tmprc) {
 // Root Cause Category field defined but ensure both parts of its cascading field are selected
 rotCausEntered = ((tmprc.get(null) != null) && (tmprc.get("1") != null))
 }

//in particular is is the following bit of code causing the error

(tmprc.get(null) != null)

When you say "assembled using make" what does that mean? Can you slim it down to a representative sample?

[Francisco Trindade]

Added a representative sample.

It's the it that's causing this, you say? As in the it variable that exists inside of a Groovy closure?

That's one of the known limitations of the static type checker. The types of Closure parameters cannot be inferred.

See https://scriptrunner.adaptavist.com/latest/jira/#_static_type_checking.

They can be inferred usually, eg in 

issue.subtasks.collect {it.summary }

but not in 

def c = { it.summary }
issue.subtasks.collect(c)
