Issue:
Invalid nft tokenURI breaks UI
Our UI expects a json encoded tokenURI.  But if someone is not having that, our market fails.

Example:  https://market.oceanprotocol.com/asset/did:op:4e95bb06d1342e027fcf3dea2a3030034b66fff4fa77c64369aeb99621e6b2f3

Traceback:
- decoding their nft contract (https://mumbai.polygonscan.com/address/0x6010F7fb5180b89A172b4146dAd12a998222957D#readContract) we got:

 ```
 
 So, we should always asses if tokenURI is a json encoded string or not
