I am trying to migrate the index from version 5.6 to 7.9 and seeing the below error

reason" : "failed to parse field [fields] of type [text] in document with id 'AXQd0YETZkyCPebFFOUB'. Preview of field's value: '{service=INF}'",

If i understand it correctly the field in 5.6 is not available in 7.9, i am failing to understand what field is it referring to, i cant see service in the list of the fields on either 5.6 or 7.9

Welcome to our community! 😃

Can you get the original document from the old cluster with that ID and post it? Please format your code/logs/config using the `</>` button, or markdown style back ticks. It helps to make things easy to read which helps us help you 🙂
