Azure Function with embedded files cannot be compiled in Github Actions

**Describe the bug**

I'm embedding files in Azure Function.

If the Azure function configuration Api.csproj contains:

$(AssemblyName.Replace(' ', '_'))


Github Action returns the following:

```
---End of Oryx build logs---
Oryx was unable to determine the build steps. Continuing assuming the assets in this folder are already built. If this is an unexpected behavior please contact support.
[WARNING] The function language could not be detected. The language will be defaulted to node.
The function language version detected is unsupported or invalid. The following node language versions are valid: 12, 14, 16, 18. If you are not using Azure Functions, you can skip this check by removing the 'api_location' input from the workflow file.

```

Here is the Api.csproj
```

net8.0
v4
Exe
enable
enable
Api
$(AssemblyName.Replace(' ', '_'))

```
