Why am I getting the error "If the working dimension of MAX or MIN is variable in length, it must not have zero length at runtime."?

What is the cause for error:

If the working dimension of MAX or MIN is variable in length, it must not have zero length at runtime.

What is the working dimension of MAX or MIN? How can I resolve this error?

The reason for this error is that ‘max’ and ‘min’ functions do not support variable-size empty inputs where the dimension to operate along is variable and takes on zero length at run-time.

Generally, the supported empty inputs for ‘max’ and ‘min’ functions include:

1) Fixed-size empty inputs

2) Variable-size empty inputs when the dimension to operate along has positive length

3) Variable-size empty inputs when the dimension to operate along has constant zero length

It may be helpful to make a logical decision (e.g. if else statement) before calling ‘max’ or ‘min’ function to ensure that the variable dimension is not of zero length at run-time.
