Docc convert fails in docker image with swift 6

[tverboon]

Description

I am working on a Swift docc project that consists of only manually created markdown files (--template articleOnly). No symbols or something else.

We want to convert the docc with a GitHub action for static hosting. When using the Swift 6.1 or 6.0 docker base image, this operation fails.

Using Swift 5.9 as base image, convert succeeds. Very nice! 👍

Checklist

• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue.

Expected Behavior

The docc convert operation succeeds, like it did with Docker image swift:5.9

Actual behavior

The docc convert operation failes with the following error:

Error: Error Domain=NSCocoaErrorDomain Code=512 "(null)"UserInfo={NSSourceFilePathErrorKey=/github/workspace/src/Midmid.Platform.Api.Docs/docs.docc/Resources/optional.svg, NSUserStringVariant=["Copy"], NSDestinationFilePath=/tmp/C445329D-DFCE-4573-B177-6AE338E38B10-7-00001ED6DC3F9EB7/images/docs/optional.svg, NSFilePath=/github/workspace/src/Midmid.Platform.Api.Docs/docs.docc/Resources/optional.svg, NSURL=file:///github/workspace/src/Midmid.Platform.Api.Docs/docs.docc/Resources/optional.svg, NSUnderlyingError=Error Domain=NSPOSIXErrorDomain Code=22 "Invalid argument"}

Steps To Reproduce

I will provide my scripts and docker file:

Dockerfile

FROM swift:6.1

COPY run.sh /run.sh

ENTRYPOINT ["/run.sh"]

#!/usr/bin/env bash

echo "Building documents in: $1"

docc convert /github/workspace/$1 --transform-for-static-hosting --output-dir /github/workspace/$2

echo "Build result in: $2"
