Hi @Kunal_Gupta,

This means the version defined as the “new code” period, 1.9.0, does not exist on SonarCloud.
To be able to use a given version as the new code, this version must have been scanned at least once by SonarCloud. SonarCloud can’t pull older versions from Github tags or releases, for example.

You can see the available versions on the Activity tab on SonarCloud.
