ImportJSON & TriggerAutoRefresh Errors

[WhaleHK]

Basic Copy Google Sheets from the original one prompts:

Exception: Attribute provided with no value: url
ImportJSONAdvanced @ ImportJSON.gs:217
ImportJSON @ ImportJSON.gs:68

when running ImportJSON.gs

and

TypeError: Cannot read property 'getRange' of null
triggerAutoRefresh @ TriggerAutoRefresh.gs.gs:14

when running TriggerAutoRefresh. There is also a problem with the NFT Tracker icon. When clicking it and clicking on "Get NFT Data", it gives the error message TypeError: nftData.forEach is not a function.

Not sure how to fix these errors.
