What is the best way to debug a dot script for an output image not being generated from the following command?

```auto
dot -Tps digraph.dot -o output.svg

```

The command completes without any warning and an `output.svg` file is generated in the same directory as the digraph.dot file. However, when I try and open the file in my Pycharm editor, I receive a message saying that I should try and open the svg externally to fix the format problem. Then opening the file externally, a browser opens the svg and I then get an error message  
`error on line 1 at column 1: Document is empty`  
The output.svg file appears red in pycharm as well. Unfortunately, there are no error messages to figure our what is going wrong. Is there another CLI command that I could look into for running this dot file?

**-Tps** tells dot to create a **postscript** file ([PS | Graphviz](https://graphviz.org/docs/outputs/ps/)),  
try **-Tsvg**
