Import dashboard by ID from Grafana.com -> Unexpected token u in JSON at position 0

Hi All,

I’m trying to import any dashboard by ID from Grafana.com and always get warning
Unexpected token u in JSON at position 0

I’m using the version 5.4.2

Dashboards can be successfully imported by JSON codes of files.

Also I can import dashboards by ID into old version of the Grafana (5.1.3)
