Describe the Problem

I was using point2grid for another project and was doing some double checking of my data. I discovered that when I created the MET 11-column object for Python embedding for point data, but it only had one observation (one line) in the object, Python embedding fails:

DEBUG 3: Initializing MET compile time python instance: /usr/local/met-python3.10/bin/python3
DEBUG 3: Running MET compile time python instance (/usr/local/met-python3.10/bin/python3) to run user's python script (read_one_line).
[['NA', 'NA', '20231204_000000', 44.03, -72.57, -9999.0, 'TEST_VAR', -9999.0, -9999.0, 'NA', 1.0]]
ERROR  : 
ERROR  : process_point_data_list -> The header is empty. Please check the python script and input
ERROR  : 

Interestingly, if I copy that line and create a file with 10 observations, but every line is the same, it also fails. If I change even one character on one of the lines with 10 observations, it succeeds.

Expected Behavior

At a minimum, if there is only 1 observation in the object passed, the MET tools should succeed. I'm not sure what we want the behavior to be if the user passes 100 observations that are identical.
