[TC-TIMESYNC-2.5] - python script is failing at Test Step 19

[Rajashreekalmane]

Reproduction steps

Setting up the environment :
Step 1 : cloned Connectedhomeip using mentioned command : git clone https://github.com/project-chip/connectedhomeip.git
step 2 : cd connectedhomeip
step 3 : pulled latest commit
step 4: source scripts/bootstrap.sh
step 5 : ./scripts/build_python.sh --install_wheel build-env
step 6 : source scripts/activate.sh

executed the below mentioned command to put DUT into a commissionable state,
./chip-all-clusters-app
Once DUT reach the commissionable state sent below mentioned command on TH.
rm -f admin_storage.json && python3 TC_TIMESYNC_2_5.py --discriminator 3840 --passcode 20202021 --commissioning-method on-network --paa-trust-store-path /paa_roots --storage-path admin_storage.json
