I have modified the sample code like below and it was worked

"""jsonplaceholder tap class."""

from __future__ import annotations

from singer_sdk import Tap
from singer_sdk import typing as th  # JSON schema typing helpers

# TODO: Import your custom stream types here:
from tap_jsonplaceholder import streams


class Tapjsonplaceholder(Tap):
    """jsonplaceholder tap class."""

    name = "tap-jsonplaceholder"


    def discover_streams(self) -&gt; list[streams.jsonplaceholderStream]:
        """Return a list of discovered streams.

        Returns:
            A list of discovered streams.
        """
        return [
            streams.CommentsStream(self),
            streams.UsersStream(self),
        ]


if __name__ == "__main__":
    Tapjsonplaceholder.cli()
