Connect Header Conversion Error

Hello - I have started to enable lenses s3 sink (4.2.0) wider throughout our cluster today and have hit the following error:

We have an SMT that adds the header field to the message itself when stored so we are not bothered about lenses not trying to convert them, so I tried setting store.envelope.fields.headers: false however the error still occurs.
Any insight into why it’s happening or what I could do to fix/avoid it would be appreciated :slightly_smiling_face:

Hi James,

Currently this connector doesn’t have support for these extended logical types. We have added this to our plan and will update you when this has been implemented.
