Hi together,

We use the Java SDK 5.5.0 for the OPCUA client.
when migrating to prosys java sdk 5.x we discovered the following behavior:

From an OPCUA server (not implemented in prosys – unknown which provider) we must write a complex type.
We do not know the Structure in advance, but instead we only know the field names.
Thus, we get the StructureSpecification from the DataType Node and create a new AbstractStructure using

AbstractStructure abstractStructure = (AbstractStructure) specification.toInstanceBuilder().build();

If a label name is x whose value should be set to y, we call

abstractStructure.set(x,y)

This worked fine until migrating to version 5.x
Then we receive an IllegalArgumentException at the method ‘validateField’
The reason is that the server sends us 7 field specifications with field indices 0,1,2,3,4,6,8
In my opinion thats clearly wrongly defined in the server.
However, its hard, time-consuming, and expensive to change that in the server.
Is there a way to handle this in the client side?

Essentially, I cant call any method in the AbstractStructure, neither setting nor getting values with fieldIndices 6 or 8

Many thanks for your help!
