Cannot access action ****, as that name is not a registered action for this domain

Hi,

All of sudden existing project started throwing this error without any change in any data file. I am not able to understand why it’s happening. Tried, multiple things. Still getting same error. Even I started new Rasa project, took old data, getting same error. Please help.
