Suggester phrase doesn t support field currentFieldName – How to solve this Elasticsearch exception

Briefly, this error occurs when you’re trying to use the “phrase” suggester on a field that doesn’t support it. The “phrase” suggester is used for text fields, so if the field is of a different type (like integer or date), you’ll get this error. To resolve this issue, you can either change the field type to text if it’s appropriate, or use a different suggester that’s compatible with the field type. Alternatively, you could create a new text field that contains the string representation of the current field’s values and use the “phrase” suggester on that.
