I’m getting an error when trying to create a new row into supabase.
Error:

Table schema:
`create table public.n8n_chat_histories_clean (
id serial not null,
session_id character varying(255) not null,
message_type character varying(10) not null,
clean_content text not null,
created_at timestamp with time zone not null default now(),
constraint n8n_chat_histories_clean_pkey primary key (id),
constraint n8n_chat_histories_clean_message_type_check check (
(
(message_type)::text = any (
(
array\[
'user'::character varying,
'ai'::character varying
\]
)::text\[\]
)
)
)
) TABLESPACE pg_default;
create index IF not exists idx_chat_clean_session_time on public.n8n_chat_histories_clean using btree (session_id, created_at desc) TABLESPACE pg_default;
`
All it looks like all fields variables have a value. But when I replace the “clean_content” with fixed text, there is no error.
Any idea why this is happening?
