Change path of GitHub build action - azure-web-app-service

Question

I have a GitHub Action that is using the default Microsoft template for building an ASP.Net Core app to an Azure App Service.
At the top of the action, you can declare some environment variables. I have these set as follows:
name: Build and deploy ASP.Net Core app to an Azure Web App
env:
AZURE_WEBAPP_NAME: (redacted) # set this to the name of your Azure Web App
AZURE_WEBAPP_PACKAGE_PATH: '.' # set this to the path to your web app project, defaults to the repository root
DOTNET_VERSION: '3.0' # set this to the .NET Core version to use
My issue is that the root folder doesn't contain the .csproj or .sln files. So this line is not correct: AZURE_WEBAPP_PACKAGE_PATH: '.'
I have tried changing it to AZURE_WEBAPP_PACKAGE_PATH: './FolderName/FolderName' (and many other variations), which is where the .csproj file is located, however the build still fails due to the following error:
MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.
Edit to include entire YAML file:
name: Build and deploy ASP.Net Core app to an Azure Web App
env:
AZURE_WEBAPP_NAME: (redacted) # set this to the name of your Azure Web App
AZURE_WEBAPP_PACKAGE_PATH: '../../FolderName/FolderName' # set this to the path to your web app project, defaults to the repository root
DOTNET_VERSION: '3.0' # set this to the .NET Core version to use

I ran into the same issue and found the solution on this SO answer, despite the fact that it wasn't marked as the correct.
Taking the above into account, your yaml file should look something like this:
name: Build and deploy ASP.Net Core app to an Azure Web App
defaults:
run:
working-directory: ./FolderName/FolderName
env:
AZURE_WEBAPP_NAME: (redacted) # set this to the name of your Azure Web App
AZURE_WEBAPP_PACKAGE_PATH: '../../FolderName/FolderName' # set this to the path to your web app project, defaults to the repository root
DOTNET_VERSION: '3.0' # set this to the .NET Core version to use
