Unable to parse connection url

I am trying to configure a database connection to InfluxDB but seeing this error:

URL: PUT https://vault.vault:8200/v1/database/config/influxdb-monitoring\nCode: 400. Errors:\n\n* error creating database object: unable to parse connection url"

Based on the docs the influxdb-database-plugin doesn’t have a field called “connection-url” but instead has “host”, I am passing “host”.
Any help appreciated

Can’t help if you don’t provide the actual command. Please post the full command include the connection string. Careful about exposing any secrets in a public forum but don’t mangle the whole thing just replace like-for-like.
