Describe the bug
If destMin exceeds MAX_INT64 in a path payment, it returns the error destMin argument must be of type String, represent a positive number and have at most 7 digits after the decimal
What version are you on?
13.0.0
Expected behavior
I would expect this error message to tell me that a possible issue could be that I exceeded MAX_INT64
