Hi, The error is coming from here: https://github.com/apache/ignite/blob/9c2ba403fae5079201e9df6bc7b7eea5bacdf4c0/modules/core/src/main/java/org/apache/ignite/internal/MarshallerContextImpl.java#L386 This means that the model class metadata is missing/corrupt. It is located in <work db>/binary_meta/<node id> and in <work db>/marshaller
To fix: If you have persistence enabled, destroy the cache in question (as well as all caches using this type), remove the given types from the above dirs and retry. Make sure the model class is in the class path. To determine the types in question: grep "fully qualified type name" <dirs listed above> remove -1293425677 file in the above mentioned dirs. Take a look at marshaller/-1293425677.classname0 to see what type this typeid represents. Make sure to remove it and all caches using this type. I encourage you to use the latest ignite version: https://ignite.apache.org/download.cgi#binaries Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
