File not being found. error WIX0094

[corey-Robinson1337]

I'm trying to build up an msi that will do the following when installing --

run a getEmail.exe file that uses active directory to get the currently logged in user's email and write it to a file
install an electron app that will use the created file.

here's my Product.wxs file

<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs">
   <?define CmdLineAppKeyPath="C:\Users\crobinson\Desktop\git_repos\electron-edge-js-quick-start\getEmail\bin\Debug\net8.0\getEmail.exe" ?>

   <Package Name="msi_builder" Language="1033" Version="1.0.0.0" Manufacturer="Corey" UpgradeCode="{c4b692de-47c6-4b66-acb9-84059f2a420d}" InstallerVersion="200"><MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
      
      <!-- CustomAction to run your command-line app -->
      <CustomAction Id="RunCommandlineApp" ExeCommand="[CmdLineAppKeyPath]" Execute="immediate" Return="check" FileRef="CmdLineAppExecutable" />

      <InstallExecuteSequence>
         <Custom Action="RunCommandlineApp" After="InstallFinalize" />
      </InstallExecuteSequence>
      
      
   
         <!-- Define INSTALLFOLDER directory -->
         <StandardDirectory Id="ProgramFilesFolder">
            <Directory Id="INSTALLFOLDER" Name="YourInstallationFolderName" />
         </StandardDirectory>
      </Package>

   <Fragment>
      <DirectoryRef Id="INSTALLFOLDER">
         <!-- Electron executable -->
         <!-- Command-line app executable -->
         <Component Id="CmdLineAppExecutable" Guid="{bc393684-759e-4afc-9208-60385a77a769}">
            <File Source="$(var.CmdLineAppKeyPath)" KeyPath="yes" />
         </Component>
         <!-- Add other components as needed -->
      </DirectoryRef>
   </Fragment>
</Wix>

and the full error I get when I try to build this

PS C:\Users\crobinson\Desktop\git_repos\electron-edge-js-quick-start\msi_builder> wix build Product.wxs
C:\Users\crobinson\Desktop\git_repos\electron-edge-js-quick-start\msi_builder\Product.wxs(7) : error WIX0094: The identifier 'File:CmdLineAppExecutable' could not be found. Ensure you have typed the reference correctly and that all the necessary inputs are provided to the linker.

Does anyone know why the file isn't being found?

The linker is telling you that you need a File element with Id='CmdLineAppExecutable' attribute. You don't have one.
