node-red crash using ExtensionObjectArray
Hello! I'm using client node and I have to write a Variat array into an opc-ua server. It's the same of case described here.
The variable is /HostComputer/f078 (in previous there are the exact stucture) af a moulding machine.
Browsing this variable I get this:
{
"payload":[
{
"item":{
"referenceTypeId":"ns=0;i=47",
"isForward":true,
"nodeId":"ns=2;i=115682",

},
"displayName":{
"locale":"en",
"text":"f078-Value"
},
"nodeClass":2,
"typeDefinition":"ns=2;i=906090",
"value":null,
"dataType":"Variant"
}
},

my target is f078-Value ns=2;i=115682 and the type is ns=2;i=906090
Browsing custom types I get:

Checking the sources I seem to understand that typeId have to be filled in "Item" but there are no check about this. If I add typeId
I get a crash with a different message:
