[Bug][OPC-UA]: org.apache.plc4x.java.spi.generation.SerializationException: Error writing signed byte

[axelweinz]

What happened?

Specifying the server certificate file in the connecting string results in org.apache.plc4x.java.spi.generation.SerializationException: Error writing signed byte.

The server certificate file format is .der.

String connectionString = "opcua:tcp://localhost:4841?discovery=false&username=admin&password=admin&server-certificate-file=PATH_TO_SERVER_CERTIFICATE_FILE.der&security-policy=Basic128Rsa15"
try (PlcConnection plcConnection = PlcDriverManager.getDefault().getConnectionManager().getConnection(connectionString)) {
  ....
}

If I omit the server-certificate-file parameter, I instead run into this error: java.util.concurrent.CompletionException: java.lang.RuntimeException: java.lang.NullPointerException: Cannot invoke \"org.apache.plc4x.java.opcua.readwrite.PascalByteString.getLengthInBits()\" because \"this.receiverCertificateThumbprint\" is null
