Error composing call using latest substrate #344
Comments
I'm not sure which runtime you are connecting to, but it seems the parameter structure changed/is incorrect for that call. What you can do is to check the composition of the params for that call: https://polkascan.github.io/py-substrate-interface/usage/extrinsics/#type-decomposition-of-call-params More information how to interpret that info: https://polkascan.github.io/py-substrate-metadata-docs/ If your runtime is already listed there you can directly lookup the call param composition info. |
Seems like on latest polkadot if a call has like a vector of something (some objects) as input, the input needs to be wrapped with another |
That is indeed strange. I can examine the structure in the |
I ran some tests on the product endpoint I found on the tfchain Github, I could compose the call above as followed: Retrieve the type composition with: call_function = substrate.get_metadata_call_function("TfgridModule", "create_node")
params = call_function.get_param_info()
# {'farm_id': 'u32', 'resources': {'hru': 'u64', 'sru': 'u64', 'cru': 'u64', 'mru': 'u64'}, 'location': {'city': 'Bytes', 'country': 'Bytes', 'latitude': 'Bytes', 'longitude': 'Bytes'}, 'interfaces': [{'name': 'Bytes', 'mac': 'Bytes', 'ips': ['Bytes']}], 'secure_boot': 'bool', 'virtualized': 'bool', 'serial_number': (None, 'Bytes')} Then entered some dummy data: call = substrate.compose_call("TfgridModule", "create_node", {
'farm_id': 1,
'resources': {'hru': 1, 'sru': 1, 'cru': 1, 'mru': 1},
'location': {'city': 'Test', 'country': 'Test', 'latitude': 'Test', 'longitude': 'Test'},
'interfaces': [{'name': 'Test', 'mac': 'Test', 'ips': ['Test', 'Test2']}, {'name': 'Test2', 'mac': 'Test2', 'ips': ['Test', 'Test2']}],
'secure_boot': True, 'virtualized': True, 'serial_number': None
})
