Steps to reproduce:
- Create a Script item with body return value; and one parameter, name = 255 characters i.e.
111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
value = any
- Test item in configuration window
- Observe Value = {} instead of the parameter object.
Result:
At the same time, data collection works fine:
Debug:
Request sent to server
{
"request": "item.test",
"sid": "<frontend session id>",

"params": "return value;",

}
Server log for the same request:

Response returned to the frontend:
{"response":"success","data":{"item":{"result":"{}","eol":"LF"},"preprocessing":{"steps":[],"result":"{}"}}}
The same request with a 254-character name returns the full object.
