I could not find the encrypted mask value.
I believe the encrypted amount is in the ecdh part:
"ecdhInfo": [
"amount": "f350bbedb3a4a93b"

As of the March 2019 hard fork, commitment masks are deterministically derived from the per-output shared secret, and the amount is XOR encrypted using a key deterministically derived from the shared secret.
See the commit here: https://github.com/monero-project/monero/commit/7d375981584e5ddac4ea6ad8879e2211d465b79d
Therefore, to determine the commitment mask, calculate:
commitment mask = Hs("commitment_mask" || Hs(8aR||i)G))
to decrypt the amount, calculate:
amount = 8 byte encrypted amount XOR first 8 bytes of keccak("amount" || Hs(8aR||i)G)
