nimble doc fails with exception "Can't obtain a value from a none [UnpackError]"

[snej]

I'm developing a Nimble package and finished adding a bunch of doc-comments.
When I run nimble doc, it immediately fails with what looks like an internal error.

Example

At a shell prompt, in my package's root directory, I enter nimble doc.

Current Output

options.nim(185)         get
Error: unhandled exception: Can't obtain a value from a `none` [UnpackError]

Expected Output

Expected the documentation to be compiled.

Extra Info

My .nimble file just looks like:

# Package
version       = "0.1.0"
author        = "...."
description   = "...."
license       = "Apache-2.0"
srcDir        = "src"

# Dependencies

requires "nim >= 1.2.0"

The error output includes options.nim -- I don't have a source file of that name. I do have one source file that imports the options module, though.

Current Output

Is this the full output? If yes then this seems to be a nimble bug rather than a nim bug.

[snej]

Yes, that's all she wrote :/
If I run nim doc path/to/file.nim for each source file individually, it works.

[alaviss]

This is a nimble bug then.

@narimiran please move the bug to nim-lang/nimble.

@narimiran please move the bug to nim-lang/nimble.

I don't have admin rights for that repo, I cannot move it there.

This isn't Nim related.
