Hi All, I created a custom tap following, https://meltano.com/blog/how-to-build-a-custom-extractor-with-meltano/ and added mongodb target. can see the run flow working but state isn't getting updated. I set the state backend to filesystem and saw that bookmarks is not getting filled.

{
  "completed": {
    "singer_state": {
      "bookmarks": {
        "files": {}
      }
    }
  },
  "partial": {}
}

I think that blog post leaves a few things out for simplicity:

You can leave the capabilities and settings fields blank for now.

You might wanna enable the

state

capability on the tap: https://docs.meltano.com/reference/plugin-definition-syntax#capabilities

Thanks @Edgar Ramírez (Arch.dev) , added the capability but bookmarks seem to be not updating still.

saw this documentation:

Declares that the plugin is able to perform incremental processing using the

--state

CLI option.

but running it with

meltano run

is giving

Error: No such option: --state Did you mean --merge-state?

where should this

--state

be added?

Does the

files

stream in your custom class declare a

replication_key

?

appreciate you for helping always, thank you so much!! @Edgar Ramírez (Arch.dev)
