Unfulfilled amount error

[34r7h]

blockfrost has had some hiccups recently.. not getting 'some' balances updated and such. this might be the issue as well. i made a ticket with them and they responded that they knew the issue and it should be solved but i didn't ask about the indexing issue.

It seems to me that the failed transaction pasted above doesn't satisfy the minimum lovelace amount.
See this output:

You attached a NFT to it, but it only has 1ADA, which can't hold any multi-asset. If you try 1.5 ADA, it may work.

[34r7h]

I'm not following yet.. the address has a total of 14 ada in 3 utxos but the builder isn't taking from the available txs. I've tried sending various amounts big and small and keep getting an insufficient amount error, hence falling back to building a raw transaction for token txs.

I think the problem you posted is not caused by utxo selection. UTxO selection doesn't necessary select all available UTxOs. Instead, the problem might be that you were trying to send an asset with only 1ADA, which is insufficient according to the min lovelace rule. Also, could you please post the entire log, including the actually exception being thrown and the Transaction input and output. It is not easy for me to guess what the real problem is without complete information. Thank you!

[34r7h]

Sure, stout for utxos, builder, and error message below. I upped the lovelace to 3,000,000 in this example.

Notice the input holding the nft has only 1.3 ada but there's more than sufficient amounts of lovelace in the following 2 utxos to cover the 3 ada + tx fee. The builder is only taking the first utxo as an input which does not have a sufficient amount to cover the total tx amount.

btw, pip is still serving pycardano version 0.5.0 which I don't think contains your latest commits. Is there a chance that this issue is already fixed in your recent work?

[cffls]

I added the example you provided as a unit test in this example here, which has passed. At the moment, I don't know how to reproduce the issue you encountered. I will look further if you could provide a runnable python script that can reproduce the issue you described.

[cffls]

Closing this issue as there is no update for a month. Please feel free to reopen this if you could provide a runnable python script that can reproduce the issue. Thanks!
