The error you are facing @pradeep is due to a change of location of an item or source in your import process.
But don't worry if you check all of the elements involved in the import process you will be able to resolve it.
This could be due to many different reasons.
If the import is from a data hub you should check the import action associated with this error.
Go to the action and use 'edit' if an error appears it means the link is likely to be broken and you will need to recreate the import process.
If this is not the case and a pop up appears showing the options for the creation of the import you should check to see if there any yellow ! marks by any mappings as this could be an error and then again you will need to re-create the import process.
Alternatively you should check the source module / file and make sure it agrees with the module you wish to import it into.
