Exceptions when adding to IPFS are printed rather than raised

[dhruvshettty]

Expected Behavior

Creating a CID hash and publishing on IPFS should raise an exception if an incorrect path or non-existent file name is provided.

Current Behavior

The exception is printed rather than being raised and halting normal execution. The metadata creation continues with the URL = null.
