starter projects can not be loaded into database

Bug Description

When I deploy Langflow 1.7.1 on Kubernetes cluster, the starter projects can't be loaded into database.
This issue is found with both of postgresql and sqlite database.

NOTES: No similar issue with langflow 1.6.9

When I enable debug log, get below messages:

Reproduction

1. Run langflow with statefulset on Kube v1.33 (the below part is securityContext of statefulset)

          securityContext:
            allowPrivilegeEscalation: false
            capabilities:
              drop:
                - ALL
            privileged: false
            readOnlyRootFilesystem: true
            runAsGroup: 1000
            runAsNonRoot: true
            runAsUser: 1000
            seccompProfile:
              type: RuntimeDefault

If I set readOnlyRootFilesystem with false, this issue is disappeared.

Expected behavior

starter projects can be loaded into database, display from web console
