Attribute Computation Error

Hi Anton,

I have built the server from the latest source code and have the below error on a Teltonika device. Please assist.

2020-05-25 15:15:17  WARN: Attribute computation error - / - ArithmeticException (... < ComputedAttributesHandler:105 < *:123 < BaseDataHandler:27 < ... < *:29 < ... < *:29 < ... < *:29 < ... < *:29 < ... < ExtendedObjectDecoder:60 < ...)

Probably means invalid expression or missing inputs.

Thanks Anton, would any of the numbers in the warning indicate which attribute/s are affected?

In my case the whole log is:

There is a special character(×) in the request parameters instead of the ampersand:

How can i solve this @Anton Tananaev ?

Seems like you are talking about 2 completely different issues.

Thanks for the response Anton.

I will open a new thread for this issue.
