Mapper_parsing_exception when migrating index from 5.6 to 7.9

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

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 :slight_smile:

Please mark this question as resolved, i migrated the index to 7.6 and didnt see the error popup again, ty!
