Briefly, this error occurs when you try to index a field in Elasticsearch with more than two dimensions. Elasticsearch supports only one or two dimensions for fields. To resolve this issue, you can either flatten your data structure to two dimensions or less before indexing, or split the data into multiple fields each containing two dimensions or less. Another option is to serialize the multi-dimensional data into a format like JSON or base64 and store it as a string field.
