ORA-19592: wrong string conversation type

What triggered the Error:

u attempted to specify a type of file to be backed-up or restored, but the current conversation cannot process this type of file. For example, you specified an archived log to be included in a datafile backup set. The specified file will not be included in the backup or restore operation.

What should we do to fix it:

action required - the conversation is still active, and more files can be specified.
