Hi,

I am developing a Jenkins plugin and I am stuck with the below issue.

Uncaught TypeError: Cannot read property 'firstChild' of undefined
at updateListBox (select.js:8)
at select.js:79
at h (hudson-behavior.js:1295)
at refillOnChange (hudson-behavior.js:1310)
at select.js:77
at Array.forEach (<anonymous>)
at behavior.js:111
at Array.forEach (<anonymous>)
at behavior.js:107
at Array.forEach (<anonymous>)

This works fine in jenkins version : 2.7.3 But, I get the above error when I load the plugin in any higher version of jenkins.

The plugin is generated using maven version : 3.* and jdk version : 1.8

Please help us to resolve this issue.

Thank You
