Deno.readFile broken?

For some reason I can't read a file with Deno.readFile. I've tried relative and absolute paths. I can cat the file without issues. Here's the relevant snippet:

...
async function fixImport(
  file: string,
  line: number,
  char: number,
  broken: string
) {
  const fixed = broken + ".ts";

  // open the file and replace 'broken' with 'fixed'
  const relative = file.replace(Deno.cwd(), ".");

  const decoder = new TextDecoder();
  const bytes = await Deno.readFile(relative);
  const content = decoder.decode(bytes);

  ...
}
...

...
async function fixImport(
  file: string,
  line: number,
  char: number,
  broken: string
) {
  const fixed = broken + ".ts";

  // open the file and replace 'broken' with 'fixed'
  const relative = file.replace(Deno.cwd(), ".");

  const decoder = new TextDecoder();
  const bytes = await Deno.readFile(relative);
  const content = decoder.decode(bytes);

  ...
}
...

and the output including cat:
