Cdhblueprint generation - Invalid Name

Hey guys, I have imported the .cdhblueprint in version 25 but I have got this error. However all my actions, groups and stuff starts with a vocal or consonant, and not a “point”. Any solution?

Error occurred while generating rules, Create new record failed: The name you entered is not valid. A valid name starts with an alphabet and contains alphabets, digits or underscores.
.pyRefToFocusKey: The name you entered is not valid. A valid name starts with an alphabet and contains alphabets, digits or underscores.
.pyFlowType: The name you entered is not valid. A valid name starts with an alphabet and contains alphabets, digits or underscores..

I recommend the following steps,

  1. download the latest blueprint component and try again.

  2. Do Customize Build instead of Build now - Ensure the application name, Case Type, Data types doesn’t have any special characters
