Error in MultiChain version 19, createrawtransaction with permissions

Question

ultichain-cli chain2 createrawtransaction '[{"txid":"...","vout":0}]' '{"...":{"permissions":{"type":"send,receive,connect","startblock":0,"endblock":4294967295}}}'
{"method":"createrawtransaction","params":[[{"txid":"...","vout":0}],{"...":{"permissions":{"type":"send,receive,connect","startblock":0,"endblock":4294967295}}}],"id":1,"chain_name":"chain2"}

error code: -8
error message:
Negative value for permissions startblock

Answer 1

This is probably a bug where the endblock value is being read as signed from the JSON-RPC request, rather than unsigned. We'll check into it for the next alpha.

For now the workaround is either to use a small maximum block number (up to 2000000000 should hopefully work) or even simpler, just omit the startblock and endblock parameters, since the defaults are the values you provided.

Answer 2

FYI this should be fixed in alpha 20, just released.
