BabbageOutputTooSmallUTxO Error

I got it to work by replacing the min_val method result with a raw number (2000000). I guess the builder needs to have an absolute minimum in the min_val method

Hi @34r7h , it is indeed a bug, which I fixed in this commit. You can try again with your old code and let me know if the problem is fixed.

Also, you can try using the post-alonzo min lovelace calculation by changing your code from:

min_val = min_lovelace(chain_context, amount=Value(0, my_nft))

to

min_val = min_lovelace(chain_context, output=TransactionOutput(to_address, Value(0, my_nft)))

where to_address is the address to which the nft will be sent to. The post-alonzo calculation requires less amount of min lovelace compared to pre-alonzo.

Seem like the issues is not fixed in the builder. We still have the same problem. Minval in the utxo is very low which is not enough.

@hasonhai Could you try using the second solution in v0.6.3?

min_val = min_lovelace(chain_context, output=TransactionOutput(to_address, Value(0, my_nft)))

6.3 with min_val = min_lovelace(chain_context, output=TransactionOutput(to_address, Value(0, my_nft))) worked. Thank you Jer

Thanks @34r7h for confirming! Closing this issue.
