How to calculate bakingRewards from tx_logging db entry?

Node
1

Please have a look at the output of the wallet-proxy API for a baker (json). For a [‘details’][‘type’] == bakingReward ‘transaction’, there is a ‘total’ field defined. This is the baking Reward for this particular baker for baking this block.

When we request transactions from the tx_logging db, we get the following output (for one of the bakingRewards):

Note that there is no ‘total’ field, unfortunately.
What is the correct way (if possible at all) to re-calculate the ‘total’ field from this list of bakerRewards?

The BakingRewards event lists the amount sent to each rewarded account. (That is to say, it’s a single event in which multiple accounts are credited.) When you query transactions for a specific account, the wallet proxy extracts the amount for the requested account and shows that as the total in its response.

That was much easier than expected, thanks!
