Hey all! I have added the S3 State Backend to my pipeline config.

tap-mysql target-s3

I managed to get it to run successfully, once, and state was stored in a

meltano-state

folder. Unfortunately I ended up with my files in

<s3://my-test-bucket/meltano-state/meltano-state/><state files>

because I had set the S3 Uri to

<s3://my-test-bucket/meltano-state/>

After I'd cleaned this up I reran the pipeline but received this message which must be related to the fact there are no state files but I'd expect the pipeline to start from scratch gracefully:

[info     ] Reading state from AWS S3

[info     ] Found credentials in environment variables.

[error    ] Cannot start plugin tap-mysql: argument of type 'int' is not iterable

[error    ] Block run completed.

I tried running again with

--full-refresh

but it also failed - I assumed this would not require State intially.

[info     ] Writing state to AWS S3
[info     ] Found credentials in environment variables.
[warning  ] Unable to persist state, or received state is invalid, incremental state has not been updated
[info     ] Block run completed.

Can anyone suggest how to resolve this?
