问向量数据库中向量维度不匹配？

 index = Index(
    FilterIndex(name = 'id',field_type=FieldType.String,index_type=IndexType.PRIMARY_KEY),
    FilterIndex(name='bookName',field_type=FieldType.String,index_type= IndexType.FILTER),
    VectorIndex(name ='vector',dimension=768,index_type=IndexType.HNSW,
                metric_type=MetricType.COSINE,params=HNSWParams(m=16,efconstruction=200))
)
                
                
ebd = Embedding(vector_field='vector', field='text', model= EmbeddingModel.BGE_BASE_ZH)
