It look's like both of these transaction's https://cardanoscan.io/transaction/f9ed2fef27cdcf60c863ba03f27d0e38f39c5047cf73ffdf2428b48edbe83234 and https://cardanoscan.io/transaction/08a7e98294857cf2500f421943ec005f0ed4825c96504ab0cefe1fbb60018df8 do indeed have collateral set.

I should note however, it does appear that this transaction failed, https://cardanoscan.io/transaction/f9ed2fef27cdcf60c863ba03f27d0e38f39c5047cf73ffdf2428b48edbe83234 and collateral was taken from the wallet.

Am I doing something wrong with my config, or is there an issue with getting collateral? I'm expecting that the collateral_inputs should not be null for a successful or failed transaction, and collateral_output should be null for a failed transaction. If i'm understanding this correctly.

I would also expect that collateral_input_count and has_collateral_output be correct as well.

Any assistance or feedback would be appreciated!

Note: I'm assuming that collateral_inputs and collateral_outputs would assist me in determining whether a transaction has failed? Please let me know if there is another way to detect a failed transaction.
