(<unknown>): mapping values are not allowed in this context at line 13 column 30

I tried this for the first time. I just copy & pasted the YAML file from the doc. When I pushed the source, GitHub sent an email to me saying an error was found in the YAML.

I tried YAML Lint

It said

(<unknown>): mapping values are not allowed in this context at line 13 column 30

What should I do?

I thought that at the LINE#13 I need to insert a line of with: as follows

      - uses: actions/checkout@v2
        with:
          persist-credentials: false

By this, it seems I could make the YAML syntactically valid.

However, after the change I mentioned above, no errors appeared, but I could not see the code file embeded in my README.md. Maybe I made something wrong. But I miss any clue what should I do next. Any advise to find my error?
