uuidv4 generates a unique identifier string.
The ID is a generated and formatted as required by RFC 4122 section 4.4, producing a Version 4 UUID. The result is a UUID generated only from pseudo-random numbers.
This function produces a new value each time it is called, and so using it
directly in resource arguments will result in spurious diffs. We do not
recommend using the
uuidv4 function in resource configurations.
