Area code is not set in setup upgrade command installing data

Question

setup upgrade command throws error while Installing data Area code is not set. The issue is coming from webkul core module. Anybody faced similar issue?

Answer 1

Fixed! I added this in installData.php

• protected $state;
• \Magento\Framework\App\State $appState in __construct params
• $this->state = $appState;

And below code in start of install() function:

try{
        $this->state->getAreaCode();
    }
    catch (\Magento\Framework\Exception\LocalizedException $ex) {
        $this->state->setAreaCode('adminhtml');
    }
