main.ERROR: Environment emulation nesting is not allowed. [] []

Question

I got an error in system.log

Why this came and how to fix this?

Answer 1

First, you need to find out that from which email this issue happening.

If you have using startEnvironmentEmulation() in your custom email then you should ensure that run stopEnvironmentEmulation () for emulated environment after doing your work.

May be stopEnvironmentEmulation is not called at your code.
