scala - Avro4S : Could not find implicit value for parameter builder -

i using avro4s

https://github.com/sksamuel/avro4s

i wrote code

implicit val schema = avroschema[salesrecord] val output = avrooutputstream[salesrecord](new file(outputlocation)) output.write(saleslist) output.flush output.close 

but compile time error

could not find implicit value parameter builder: shapeless.lazy[....] not enough arguments method apply  

there bug in 1.2.x private vals in case class caused error you've seen here. that's fixed in 1.3.0 , should solve problem.

(if it's not private vals, you'd need post salesrecord object take @ , i'll update answer solution).
