Dear Anita Ngai,
Good day!! Wish you a happy new year~
I understand your concern and as per the attached screenshot, you have entered the List URL in the Site Address instead of the Site URL where the Lists are stored. Since the URL entered is your OneDrive for Business, the URL will be looking like https://m365x8****8-my.sharepoint.com/personal/c***u_m365x8***8_onmicrosoft_com
So, I request you remove the /Lists/Test%20tracker2 in your Site Address and check whether the Lists in your Microsoft Lists are populated.
If the same problem persists with your Power Automate flow, I would like to request you to post your concern in the Microsoft Power Automate Community - Power Platform Community to get the detailed help from the experts.
Apologies for redirecting you to different community as the members in the category posted focus on the users with the out of the box concerns and have limited knowledge on the custom Power Automate flow, so to get the fast and better assistance, we have redirected you in the correct path.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
