Can't change my asset's description

Hi everyone, i’ve just created an asset and i’m trying to change it to my new JSON descriptor, but counterwallet gives out a cryptic error message:

“Error making request to undefined: Unknown Error.”

And when checking the network tab on debug view, there’s no error message to be seen either.

I have BTC balance (~0.0083) and some XCP (1.325).

The json descriptor is this one.

Any help would be appreciated

Welp, it seems it’s just the description length. Changed the server name and it worked.

What is the maximum description length?
