Grafana 9.1.3 impossible to connect a datasource from Influx 1.8.10

Since the update (from 9.0.1 to 9.1.3), it’s impossible to create new data sources in Grafana when database is new db from InfluxDB 1.8.10.

After several tests I must to downgrade Grafana to 9.0.8 (August 30, 2022)
I think that a little regression.

Can you help for this problem. Without the solution it’s impossible to upgrade version of Grafana.
