Unexpected end of JSON input

[preethidh]

My code : P.S., I am trying to print the output in .md file

  - name: Overwrite file
    uses: testing/POC@master
    with:
      file: './Data.md'
      write-mode: overwrite
      contents: |
        "${{ steps.chart-name.outputs.data }}"

Error :

Warning: Unexpected input(s) 'write-mode', 'contents', valid inputs are ['file', 'key-path']
Run testing/POC@master
with:
file: ./Data.md
write-mode: overwrite
contents: "chart name"

Error: Unexpected end of JSON input
