Azure trusted signing error

[Kitenite]

• Electron-Builder Version: 25.1.8

• Node Version: 20

• Electron Version: 33.2.1
• Electron Type (current, beta, nightly): current

• Electron updater Version: ^6.3.4

• Target: Windows

I'm running into a very opaque error on github actions using version 25.1.8:
Invoke-TrustedSigning: Cannot process argument transformation on parameter 'FilesFolder'. Cannot convert value to type System.String.

I've added my env variables using this guide.

My env variables are confirmed created and seem valid.

echo "AZURE_TENANT_ID=${{ secrets.AZURE_TENANT_ID }}" >> $GITHUB_ENV
echo "AZURE_CLIENT_ID=${{ secrets.AZURE_CLIENT_ID }}" >> $GITHUB_ENV
echo "AZURE_CLIENT_SECRET=${{ secrets.AZURE_CLIENT_SECRET }}" >> $GITHUB_ENV

I've also set up my config as well

win: {
        target: [
            {
                target: 'nsis',
                arch: ['x64'],
            },
        ],
        signtoolOptions: {
            publisherName: 'On Off, Inc',
        },
        artifactName: '${productName}-setup.${ext}',
        azureSignOptions: {
            publisherName: 'On Off, Inc',
            codeSigningAccountName: 'trusted-onlook',
            certificateProfileName: 'public-trust-onlook',
            endpoint: 'https://eus.codesigning.azure.net',
        },
    },

The error:
