Parse functionality not working

[mikias21]

I am using the docker container of gumtree. Trying to parse a C code and generate AST but not working.
I tried these two commands but both of them throw error. Can someone help me with this issue please?

└─$ sudo docker run -p 8000 gumtreediff/gumtree parse ~/Desktop/research/snippets/gumtree/orignal/test.c
