'ERC721PresetMinterPauserAutoId tokenURL error
I am working on writing ERC721 smart contracts by using the PresetMinterPauserAutoId script.
ERC721PresetMinterPauserAutoId("Simple", "SPL", "http://127.0.0.1:8080/ipfs/QmU2JdyAmcSMy9A44nUCbYCFkKKR65b37HCqZLsQPNJABw/")
{}
However, for the third parameter in the constructor (supposing it's the base url), I am not sure what to put. I tried "ipfs://{CID}" , "http://ipfs/{local site}/{CID}" and "ipfs.io/{CID}" but they all failed. I wonder how am I supposed tyo get my json data read and if there's any way to test what the input actualy is (in order to debug). Thanks.
