DynamicFrameWriter fails to parse jdbc URL query params

[jon-laf-nexient-numo]

I encountered an error while using the Glue library's DynamicFrameWriter class.

Stacktrace fragment:

Note the exception at the bottom of this Stacktrace excerpt:

The connection property 'sslMode' acceptable values are: 'DISABLED', 'PREFERRED', 'REQUIRED', 'VERIFY_CA' or 'VERIFY_IDENTITY'. The value 'REQUIRED?useCursorFetch=true' is not acceptable

It appears that Glue appends the query parameter ?useCursorFetch=true under the hood, but fails to parse the query parameter ?sslMode=REQUIRED that was part of the sink jdbc url passed to connection_options argument in the method GlueContext.write_dynamic_frame.from_jdbc_conf.
