wt create --bundle throws "invalid semver for module"

[Salketer]

Hello, I am trying to bundle my first real task. This task has a package.json file that has this dependency:

"piexifjs": "^2.0.0-beta.7"

This returns this error:

Uncaught error:  invalid semver for module piexifjs (2.0.0-beta.007) at '.modules'

I have tried with many different semver but they either are not working because they are not available from NPM, or throw this error.

To me, this is happening because of the padded 0 after the beta part.

From Semantic Versioning 2.0.0

A pre-release version MAY be denoted by appending a hyphen and a series of dot separated identifiers immediately following the patch version. Identifiers MUST comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-]. Identifiers MUST NOT be empty. Numeric identifiers MUST NOT include leading zeroes.

What I don't understand is where those are coming from? They sure are not in my package.json, I even tried looking at my package-lock.json!

EDIT:

node --version
v8.11.3
npm --version
5.6.0
wt --version
11.0.0
