@Wolfgang1963 Supabase expects the query text to come in a field literally named “input” (the prompt/search string). So you must map your workflow data into an input property before the vector search. Otherwise, Supabase rejects it with that error.

Hi @Wolfgang1963

That error means the data reaching Supabase does not include a field named exactly input at execution time.

Check the node immediately before Supabase and make sure it outputs a JSON like:

{
  "input": "your search text"
}

If your workflow uses a different field name, add a Set node to rename it to input, or map it explicitly using an expression.

After that, re-run the workflow. No other configuration changes are needed.

If it still fails, inspect the incoming data to the Supabase node and confirm the input field exists and is not empty.
