The below code is working:

[ec2-user@ip restore]$ echo $snap_name
manual-test-2024-01-11-11-26-19
[ec2-user@ip restore]$  aws rds describe-db-cluster-snapshots --db-cluster-identifier creditpoc3 --query 'DBClusterSnapshots[].{DBClusterSnapshotIdentifier:DBClusterSnapshotIdentifier,Status:Status} | [?DBClusterSnapshotIdentifier == `'"$snap_name"'`']'' | grep creating
[ec2-user@ip-10-0-39-226 restore]$

[ec2-user@ip restore]$ echo $snap_name
manual-test-2024-01-11-11-26-19
[ec2-user@ip restore]$  aws rds describe-db-cluster-snapshots --db-cluster-identifier creditpoc3 --query 'DBClusterSnapshots[].{DBClusterSnapshotIdentifier:DBClusterSnapshotIdentifier,Status:Status} | [?DBClusterSnapshotIdentifier == `'"$snap_name"'`']'' | grep creating
[ec2-user@ip-10-0-39-226 restore]$

But when trying to get the output as a variable, it is getting an error:

[ec2-user@ip restore]$ snap_count=`aws rds describe-db-cluster-snapshots --db-cluster-identifier creditpoc3 --query 'DBClusterSnapshots[].{DBClusterSnapshotIdentifier:DBClusterSnapshotIdentifier,Status:Status} | [?DBClusterSnapshotIdentifier == `'"$snap_name"'`']'' | grep creating`
