Hey Leandro, I'm not sure that I completely understand what you're trying to do - you want to populate the 'base64' field? What value are you trying to populate it with?

Now the next question: how to write to these sub records a distinct value per record found? I'm using /attachments/values[*]/base64 as Result RecordPath, however it doesn't seem right. If one value is found, it gets written to all sub records. And if more than one value is found (from the query you helped me build), then nothing is set. Hoping this is easy to fix, just like the previous obstacle. Thank you!

Have a complex schema that involves records and maps. This is my Avro Schema: { "type": "record", "name": "Contact", "fields" : [ {"name": "id", "type": "string"}, {"name": "firstName", "type": "string"}, {"name": "lastName", "type": "string"}, {"name": "fullName", "type": "string"}, { "name" : "attachments", "type" : { "type" : "record", "name" : "attachments", "fields" : [ { "name" : "keys", "type" : { "type" : "array", "items" : "string" }, }, { "name" : "values", "type" : { "type" : "map", "name" : "attachments", "namespace" : "values", "values": { "type" : "record", "name": "attachments", "namespace": "attachment", "fields": [ {"name": "id", "type": "string"}, {"name": "value", "type": "string"}, {"name": "filename", "type": "string"}, {"name": "type", "type": "string"}, {"name": "base64", "type": "string"} ] } }, } ] } } ] } Here's an input example: { "id" : "1234", "firstName" : "Leandro", "lastName" : "Silva", "fullName" : "Leandro Silva", "attachments" : { "values" : { "68e0ccf7-a021-4797-b9be-48d4eab0f2db" : { "id" : "68e0ccf7-a021-4797-b9be-48d4eab0f2db", "value" : "https://example.com/file.pdf";, "filename" : "file.pdf", "type" : "pdf" } }, "keys" : [ "68e0ccf7-a021-4797-b9be-48d4eab0f2db" ] } } And I'm trying to get the property value inside attachments. I've tried the following: /attachments/values['68e0ccf7-a021-4797-b9be-48d4eab0f2db']/value (which works) However I need to get all URLs inside this record and the keys are not static. Tried /attachments/values[]/value (but doesn't work. Unexpected token ']') //value (doesn't work, most probably because there's a map in between) /attachments/values/*/value (doesn't work) /attachments/values//value (doesn't work) The second step would be to write back to a new property inside this same structure, but I am a bit far from there. Any ideas? All help is very much appreciated. Thank you. Leandro Lourenco
