How create scripts and trends by script ?

[buuuudzik]

First 6 trends are successfully created but another not and there is such res:

Code:

* arg: 2
 * string: {"size":true,"success":false}
* arg: 3
 * number: 200

What means "size": true? I have enought space on LM and also RAM is ~50%.

I've tried also to add trend via Editor and there is such error. I didn't know that there is a limit in trends? I have only 24 trends on this LM.
