  • Fixed an issue with the OPC UA Browse Snap where the original document was missing for few error view records.
  • Fixed an issue with the OPC UA Read Snap that displayed incorrect data when reading from Structure data type nodes.
  • Removed expression support for the Subscription type to ensure accurate display of Data change filter properties in the OPC UA Subscribe Snap.
  • The Value field is now mandatory in the OPC UA Write Snap.

    Fixed the following issues in the OPC UA Write Snap:
    • Bad_WriteNotSupported error when writing specific values (for example, Float) to nodes on ANSI C-based OPC UA servers.
    • Empty strings being coerced to null because of platform annotation.
    • Incorrect data type conversion for multi-dimensional arrays.
    • Improper handling of null values for ByteString types.
    • An exception error when passing an invalid value (such as a non-numeric string) for Batch size using pipeline parameters. Now, if you pass a non-integer value for Batch size, the Snap fails during validation with a descriptive error rather than a runtime NumberFormatException.
