Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Lissa,
Thanks for your updates and providing the screenshots for our reference.
It seems that you use another way instead of Parse JSON to get the dynamic file id. You can just use the substring formula based on your data under Get file content (OneDrive for Business) to change the file names with Compose and then add them as attachments to the site list.
Welcome to share any updates at your convenience.
Thank you for your time and effort.
Sincerely
