Analyze: Execution Exception: java.lang.NullPointerException

[AmosGeorge]

Hello,
I use Paramalyzer version 2.2.2, installed from BAppStore.

After clicking the Analyze button, the analysis hangs and throws the following error in the status bar.

Execution Exception: java.lang.NullPointerException: Cannot invoke "burp.Zcu5.ZN1()" because "<local1>" is null

Here is the stack trace from the paramalyzer extension's Errors tab:
