Why aren't the offchain views appearing?

Question

I'm extending the smartpy FA2 template

# 
FA2 = sp.import_script_from_url("https://smartpy.io/dev/templates/FA2.py")
class TezosLandNft(FA2.FA2):
...

which has the following offchain views defined

# ex:
class FA2_token_metadata(FA2_core):
    @sp.offchain_view(pure = True)
    def token_metadata(self, tok):
...

However, when querying for these views using taquito, none of the offchain_views are appearing

const token_contract = await Tezos.wallet.at(WALLET_ADDRESS, compose(tzip12, tzip16));
const views = await token_contract.tzip16().metadataViews()
# views === {}

Answer 1

The issue is caused by an invalid IPFS link.

Steps to FIX the issue:

1. Update the metadata (including views, etc...)
2. Copy the generated JSON
3. Upload the metadata JSON to IPFS

You can use Pinata for this.

4. Update the metadata link in the code

Replace all occurences of sp.metadata_of_url("https://example.com") with sp.metadata_of_url("<ipfs_link>")
