The template when you create a post is actually to describe those points, please use them next time.
The error message seems pretty explicit: your number of lines exceeds your organization plan.
The analysis could not be done as it would have exceeded your current max LOC allowed.
Your solutions are either to increase your plan (https://sonarcloud.io/pricing) or remove some other projects to make room for this one.
Thank you @Antonie , We have increased our plan and code analysis is happening . we are able to see it in the activity tab . But still it gives this error message.
