Area code is not set error during setup:upgrade

[norgeindian]

I'm getting the error "Area code not set" during the setup:upgrade command.
Unfortunately, I can not really tell, why...
This is what I found out so far:

As soon as I disable this module, the error is gone and setup:upgrade runs without issues.
The exception trace is the following:

The only thing, which led me to the idea, that it could be related to this module, is the occurence of "____plugin_m2epro_plugin_config_magento_config_model_config_structure_data" in the list.

We're using https://github.com/m2epro/magento2-extension in version 1.74.1 in the project, so the problematic plugin seems to be https://github.com/m2epro/magento2-extension/blob/1.74.1/Plugin/Config/Magento/Config/Model/Config/Structure/Data.php

Does anyone have a good idea, why this leads to the "Area code is not set" issue and how I could fix it?

Usually this happens when a class runs code in its constructor that shouldn't be run automatically, like loading system config.

I glanced at the plugin class and a few of its DI dependencies but didn't see what would be causing it.

Hello, any solution for this? Also have this exact problem

[sprankhub]

For us, after updating m2epro/magento2-extension to version 1.84.0, it does not happen any more.
