Hi, In a client node that runs in a two server nodes cluster I get that error at first value that is read from an Ignite cache:
org.apache.ignite.binary.BinaryInvalidTypeException: Requesting mapping from grid failed for [platformId=0, typeId=-1293425677] at org.apache.ignite.internal.binary.BinaryContext.descriptorForTypeId(BinaryContext.java:707) at org.apache.ignite.internal.binary.BinaryReaderExImpl.deserialize0(BinaryReaderExImpl.java:1757) at org.apache.ignite.internal.binary.BinaryReaderExImpl.deserialize(BinaryReaderExImpl.java:1716) at org.apache.ignite.internal.binary.BinaryObjectImpl.deserializeValue(BinaryObjectImpl.java:798) at org.apache.ignite.internal.binary.BinaryObjectImpl.value(BinaryObjectImpl.java:143) In all the nodes Ignite is embedded in Java applications running Java 11, Spring 5 and Ignite 2.7. The server nodes are Tomcats and the client node an Spring Boot app. All the nodes have a similar classpath including the classes that are put in cache. That problem happens in an environment and doesn't happen in another with "apparently" with the same configuration. I tried to remote debug and compare what diverges between working and failing environments. And I've seen that in org.apache.ignite.internal.binary.BinaryContext#descriptorForTypeId in the line that does: BinaryClassDescriptor desc = predefinedTypes.get(typeId); In the working environment the predefinedTypes had a value for the typeId, and in the failing one doesn't. I don't have a lot of experience/knowledge of the Ignite internals. Any help or indication to point where to investigate or possible causes of the error will be very helpful. A lot of thanks in advance, -- Joan Jesús Pujol Espinar
