Syntax error running Python script in Java Process

I have a script in python that should receive two PDF files and output an image. It works fine in the terminal but when I try to run it in a Java process using process builder it gives me a syntax error and I am not sure why.

I am using python3 with the command (in the terminal):

python3 /pathToMyPythonScript/command_line.py /Users/myname/Desktop/one.pdf /Users/myname/Desktop/two.pdf > /Users/myname/Desktop/XXXXXXXXXXXXXXXXXXXXX.png

It works and produces the desired output.

also tried:

/usr/local/bin/python3 /pathtomypythonscript/command_line.py /Users/myname/Desktop/one.pdf /Users/myname/Desktop/two.pdf > /Users/myname/Desktop/XXXXXXXXXXXXXXXXXXXXX.png

and it also works fine.

When I call the same script in my java code using the following code:

Process p = new ProcessBuilder("/usr/local/bin/python3", fileOneLocation, fileTwoLocation, outputFileDestination).inheritIO().start();

all variables are declared and all files exist.

My eclipse console output is an error:

File "/Users/myname/Desktop/one.pdf", line 1
    %PDF-1.3
    ^
SyntaxError: invalid syntax

What am I missing here? It works fine in terminal but not in Java.

As an answer:

You forgot to mention your actual python script in the ProcessBuilder
