Hello I’m developing long project.

Tomorrow I open the project and try to save it without any modification,

but appears this window

 

 

Can someone please help me, thankyou in advance.

I have just installed TouchGFX-4.26.1 but it has the same problem

Do you have a custom trigger on your codebase? It seems TouchGFX is unable to serialize it because it refenrence a Null

System.NullReferenceException: Object reference not set to an instance of an object.
   at TouchGFXDomainModel.LoadSave.Serial.ToSerial.Convert(TriggerCustom t)

Most likely, one of your custom triggers is missing a required property (e.g., an action, condition, or a referenced screen/widget that no longer exists).

thankyou … I individuate the TriggerCustom

I belive the piece of the log that describes me the problem is

 

I removed interaction based on a CustomControl that I removed

 

{
  "InteractionName": "OnAesKeyCompleted",
  "Trigger": {
  "Type": "TriggerCustom",
  "TriggerCustomTypeName": "AesKeyGunGetter OnAesKeyCompleted happens",
  "TriggerComponent": "aesKeyGunGetter"
},
  "Action": {
  "Type": "ActionCustom",
  "FunctionName": "OnAesKeyCompleted"
}

 

and now it works
