Fix WrongMethodTypeException

✅ Solution

The WrongMethodTypeException in Elasticsearch ingest pipelines usually arises from a mismatch between the expected method signature (argument types and return type) of a script function and the actual method signature provided in the script. To fix this, carefully examine the script function definition and invocation within the pipeline, ensuring the data types passed as arguments align precisely with the expected types and that the return type of the script matches what the pipeline anticipates. Review Elasticsearch's scripting documentation for specific type conventions.
