Errors in Electromechanical copuling with Nernst-Planck equation

I tried to simulate the electromechanics of polymer-metal actuator (IPMC) with involve ions migration i.e. Nernst-Planck equation.
I made 2 components i.e. Studies (time dependent) with identity mapping. The first component consists of electric Current, Transport of diluted species and General Form PDE while the second components consists of solid mechanics only.
The problem is the Study 2 failed to execute due to this error:

Extrusion coupling operator interpolation failed for at least one point: no source point found.

I attach my file for your reference. Please anyone could suggest solution to this problem. I really appreciate it.

Thank you.
