Briefly, this error occurs when the profile UID you’re using in Elasticsearch doesn’t contain an underscore character. Elasticsearch uses underscores in UIDs for specific purposes, and if it’s missing, it can cause issues. To resolve this, you can modify the UID to include an underscore. Alternatively, if the underscore isn’t necessary for your use case, you can adjust your Elasticsearch settings or code to accept UIDs without underscores. Always ensure that your UIDs follow the correct format to avoid such errors.
