After executing this code to create a vctor index

    CREATE VECTOR INDEX movie_tagline_embeddings IF NOT EXISTS
      FOR (m:Movie)
      ON (m.taglineEmbedding)
      OPTIONS { 
        indexConfig: {
          'vector.dimensions': 1536,
          'vector.similarity_function': 'cosine'
        }
      }

I run into following error:
Invalid input ‘{‘: expected “+” or “-” (line 5, column 18 (offset: 131))
” indexConfig: {”
^

Any ideas? Iam new to Neo4j and can’t get it solved
