TypeError: Cannot read properties of undefined (reading 'prototype')

hi, thanks for such an amazing tool. We have been using this for a while. However, very recently we were not able to successfully execute any import or export operation because of this error.

I have got all sfdx and this pluging updated.. version of etcopydata 2.1.1

% sfdx ETCopyData import -c ETCopyData\DigitalProducts -s OUAT -d ODev --loglevel debug
TypeError: Cannot read properties of undefined (reading 'prototype')

Any idea on how to rectify this, please ?

Change the log level to Trace and review the output, the code should show more information to help debug
