thanks for the report @sivanagireddyb . I haven't looked at the code, but does using single-quotes instead of double-quotes fail w/ the same error?

[sivanagireddyb]

@hunleyd Yes, Double quotes are also giving same error. I had to use json filter and ascii format to make it work. '{{ contacts|to_json(ensure_ascii=False) }}' this worked for me.

ok thanks for the update @sivanagireddyb . we'll look into the issue and see if we can code up a fix.

@sivanagireddyb hello, thanks for reporting the issue. I'm not a Postgres JSON user.
I found on https://www.postgresqltutorial.com/postgresql-tutorial/postgresql-json/
that JSON should be inserted as a string of the format '{"key": "value"}' but I see a list in the description.

• Could you please elaborate a bit on why there's the list in the description?
• If you pass, say, the string {"email1": "[email protected]", "email2": "[email protected]"}, will it work?

thanks

@sivanagireddyb could you please take a look? ^
We're looking forward to your feedback

Even though postgress type is Json it accepts list, Which worked for me when tested with hard-coded value instead of variable.

[Andersson007]

@sivanagireddyb if you pass the string {"email1": "[email protected]", "email2": "[email protected]"}, will it work?

[sivanagireddyb]

I haven't tested it but the the format I was expecting is in list []

Using ascii filter along with json worked for me.

'{{ contacts|to_json(ensure_ascii=False) }}'
