can't merge a non object mapping [industry_g1] with an object mapping

This error message usually occurs when you try to merge a non-object mapping with an object mapping. In Elasticsearch, a mapping defines the fields and their data types in an index.

For example, if you have an index called "company" with a field called "industry_g1" that has a non-object mapping (such as a keyword type), and you try to merge it with another mapping that has an object type (such as a nested or object type), you will get this error message.

To resolve this issue, you need to ensure that the mappings you are trying to merge have compatible data types. If you want to merge an object mapping with a non-object mapping, you may need to change the data type of the non-object mapping to an object type.

Alternatively, you can create a new index with the desired mappings and then reindex your data into the new index. This will allow you to have a fresh start with the correct mappings.
