Generate arbitrary amount deposit data

By default, validator records are populated with deposit transaction data suitable for deposits of 32ETH.

This endpoint can be used in situations where you want to perform deposits of amounts other than 32ETH.

This will generate the deposit transaction data for one or more validators corresponding to the amount(s) specified in the request body.

Note that this will not replace nor invalidate the deposit data that is stored on the validator records themselves

This endpoint will return an error in the following situations:

• an invalid amount is specified (<= 0 or > 32000000000)
• one or more of the specified validators is not in a WAITING_DEPOSIT state
• one or more validators is not associated your account
• the list of specified validators contains duplicate pubkeys
