if I send the command device status it working well.
send device information:

result:

but if I send "Device Data Statistic" sign invalid.
send data statistic:

result:
code: 1004
msg: "sign invalid"
success: false
t: 1665456675946
tid: "93161241490f11eda5021297425bcc23
if I send from postman working well.

thanks
