WiX Light can't find a downloaded github actions artifact - github

Question

In one step of a github actions job, I download an artifact that was uploaded in a previous job. I see these messages in the workflow output:
Artifact Executable_file was downloaded to D:\a\pcm_pcmplatinum_u\pcm_pcmplatinum_u\PCMateSetup\PCMPLUS.exe
Artifact download has finished successfully
In a subsequent step of the same job, I run msbuild on a *.wixproj file. Candle runs without error, but Light fails with this error:
error LGHT0103: The system cannot find the file 'D:\a\pcm_pcmplatinum_u\pcm_pcmplatinum_u\PCMateSetup\.\PCMPLUS.exe'.
Here are the relevant sections of the workflow .yml file:
- name: Download executable file
uses: actions/download-artifact#v3
with:
name: Executable_file
path: ./PCMateSetup/PCMPLUS.exe
- name: Build PCMateSetup
run: |
msbuild /m /p:MajorVer="${{env.majVer}}" /p:MinorVer="${{env.minVer}}" /p:BuildVer="${{env.bldVer}}" /p:ProtoVer="0" /p:GithubBld="true" /p:Configuration=${{env.BUILD_CONFIGURATION}} /v:n ${{env.SOLUTION_FILE_PATH}}\PCMateSetup\PCMateSetup.wixproj
From the .wxs files:
<?define PCMPlus.TargetDir="$(var.ProjectDir)." ?>
<File Id="file.instDir.PCMPLUSExecutable" Vital="yes" Source="$(var.PCMPlus.TargetDir)\PCMPLUS.exe" KeyPath="yes" />
And also from the output messages:
ProjectDir: D:\a\pcm_pcmplatinum_u\pcm_pcmplatinum_u\PCMateSetup\
I see no reason why Light should be failing this way. I did try changing the WiX code to eliminate the extra backslash and period in the path to the file, but Light failed with the same error. Does anyone have any idea why Light is failing to find the file? Thanks.

In one path it's PCMateSetup and in the other path it's PCMateSetup.
