Error: 1 after trying to get notification_data

Hi I am getting error: 1 when trying to get notification_data
here is my url
https://hst-api.wialon.com/wialon/ajax. … %22col%22:[1]}&sid=ea1e2954971af3daf425394f6ca3f466

I have tried with new session ids, but it is still throwing error: 1 , even with other reques is throwing error 5 or 7, i have never experimented this, the user that i am using is my root user on gurtam sdk, so I would like if there was a change on my permissions or something and if it is, how to reslve.

Cheers!
Thanks for your attention
