I have a copper slab onto which I want to adsorb CO2. I am studying both charged and uncharged surfaces of the slab. Therefore using "ESM" boundary conditions. But I am facing the following error:</div>

AS mentioned in one of the example of ESM (<a href="https://gitlab.com/QEF/q-e/-/blob/master/PW/examples/ESM_example/run_example_ESM" id="LPlnk793155">https://gitlab.com/QEF/q-e/-/blob/master/PW/examples/ESM_example/run_example_ESM</a>) I am using all the necessary
tags like assume_isolated='esm', esm_bc='bc3', tot_charge=-1. But still facing the error. </div>

I would appreciate any suggestions regarding it. My input and output files are attached below.</div>
