This is likely due to a bug in the parser. See rcjsuen/dockerfile-ast#80.

I have the same problem, and I solved changing a character. Space " " has something strange.

@luismanuelmontoro Maybe you encountered #74? Do you still have your original Dockerfile that you can share with me?

[luismanuelmontoro]

Not, sorry.
