Getting 400 Bad Request when trying to sign document

[alekseibahmatov]

I'm using smart-id v2 with Demo credentials. Right now I'm trying to set up signing service, but everytime I try to sign any document I get 400 Bad Request.

Could this error be related to the fact that I am using the demo version of the service?

Used hash value is not valid - Bad Request

"hash":"somehash"

Should be - Base64 encoded hash function output to be signed (Base64 encoding according to rfc4648). More info https://github.com/SK-EID/smart-id-documentation#23104-request-parameters
