Input/Fullfillment

[stefanoba]

Hello, perhaps in the class Input the property fullFillment should be a class instead of String; this because before fullFilment it is of the form { 'public_key': 'key', 'type':'type'} and after fullfilment it is the signature "fulfillment": "signature",

thanks, Stefano

According to the HTTP API Docs, the fullfilment is "". I don't see any examples on the documentation that uses public_key and type before it sends it. Can you cite an example here please?

[stefanoba]

Yes I agree, but I see in the example at https://docs.bigchaindb.com/projects/py-driver/en/latest/handcraft.html, which I report here: In [127]: input_ = { .....: 'fulfillment': output['condition']['details'], .....: 'fulfills': { .....: 'output_index': output_index, .....: 'transaction_id': signed_car_creation_tx['id'], .....: }, .....: 'owners_before': output['public_keys'], .....: } .....: Or perhaps is my misunderstanding. Thanks

I have to clarify this with the core devs, but if you look at the Java code at line 313, we already create the fulfillment using the public_key so that you have to pass redundant input to the builder.

May I know what exact issue are you encountering?

I'm working to extend the driver to support transfer transaction; we need 2 outputs and this is a json before fulfillmet I send to BCDB, which I suppose to be correct. The asset is a valid trid of a create, but we obtain the followind error trying to send the transfer transaction: { "message": "Invalid transaction schema: {'output_index': '0', 'transaction_id': 'eeb34f43a04cc887e00003408c8d32f07c897734983190cc585d7620e38fcac7'} is not valid under any of the given schemas", "status": 400 }

BAD REQUEST

We think the problem is NOT in the fulfillment, however:
