GitHub Actions fails with reading JToken from JsonReader error - github

Question

I am trying to follow the How to use GitHub Actions build matrix to deploy artifacts to multiple servers tutorial. I have finished halfway through the tutorial, however, I get the following error when it builds the app.
Error when evaluating 'strategy' for job 'prepare-release-on-servers'. (Line: 53, Col: 17): Error reading JToken from JsonReader. Path '', line 0, position 0.,(Line: 53, Col: 17): Unexpected value ''
I have checked the JSON file for validation and gone through the deployment file countless times.
Here is the deploy-application.yml file.
name: Deploy Application
on:
push:
branches:
- main
jobs:
create-deployment-artifacts:
name: Create deployment artifacts
runs-on: ubuntu-latest
outputs:
deployment-matrix: ${{ steps.export-deployment-matrix.outputs.deployment-matrix }}
steps:
- uses: actions/checkout#v2

npm install
npm run prod

echo "::set-output name=deployment-matrix::$(echo $JSON)"
prepare-release-on-servers:
name: "${{ matrix.server.name }}: Prepare release"
runs-on: ubuntu-latest
needs: create-deployment-artifacts
strategy:
matrix:
server: ${{ fromJson(needs.create-deployment-artifacts.outputs.deployment-matrix) }}
steps:
- uses: actions/download-artifact#v2
with:
name: app-build
Here is the JSON file.
[{"name":"server-1","ip":"216.656.30.240","username":"root","password":"sdddssafilgwzxcxvgvggfdassa","port":"22","beforeHooks":"","afterHooks": "","path": "/var/www/html" }]
I cannot find the problem here. Any help would be nice. Thanks in advance.

Maybe you should follow the instructions of Philo article link
This code is also running deprecated commands(set-output). so you need also not to use them anymore and use the new ones.
name: Set output
run:
echo "{name}={value}" >> $GITHUB_OUTPUT
