{Error Resolution}DateTime is less than minimum value supported by CrmDateTime error in Dynamics CRM 2016 in a plugin

Recently users started randomly reporting an error when they hit a custom ribbon button on a custom entity which used to trigger a plugin.

The log they were able to download had the following error:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: DateTime is less than minumum value supported by CrmDateTime.

Issue Resolution:

A quick check on the code told the reason. A developer had set CRM Date Time field to 01/01/0001.

Smallest Date Time possible to be set in CRM is 01/01/1753.
