When does this happen?

IF SupabaseVectorStore.from_documents returns APIError '22P02' with message 'invalid input syntax for type bigint' when inserting documents after upgrading LangChain, because the database table's id column expects bigint but the library now generates UUIDs.

How others solved it

THEN Recreate the Supabase documents table with a uuid primary key instead of bigserial. Use the schema: id uuid primary key, content text, metadata jsonb, embedding vector(1536). Ensure the table matches the structure expected by LangChain's SupabaseVectorStore integration as documented. If data must be preserved, migrate existing records into the new table.

-- Create a table to store your documents
create table documents (
  id uuid primary key,
  content text,
  metadata jsonb,
  embedding vector(1536)
);
