not quite following.  Can you paste the query you are trying to
execute along with the results vs. expectation?  thanks

Still not quite following. My advice would be to:

#1) work out the SQL you want the database to be running and verify
the results are correct

#2) figure out out to get the ORM to send that SQL

If you need help figuring out that SQL the ORM is actually running,
try turning on statement logging in postgresql.conf and watching the
log.

This query converts a string into a JSON object that consist of that
string. I guess what you intend to accomplish is rather:

select jsonb_build_object('key1', 'text1', 'key2', 'text2');

never heard of your ORM... does it even know what postgres jsonb is ?   
do you know what actual SQL query that piece of ORMism generates ?
