Notes:

In previous script _add1 method of contract was called. It emits event TryEvent that produces an issue, if we try to decode the corresponding body of external out message. But if you call _add2 method instead (tonos-cli_newww/tonos-cli/target/release/tonos-cli -j call --abi 1_Accumulator.abi.json $addr add_2 '{"value":"101"}' --sign key.json), it will be ok in the end. And one gets the following output. So it looks like decode body command work is unstable?

tonos-cli -j decode body  --abi 1_Accumulator.abi.json "$body"
{
  "BodyCall": {
    "TryEvent_1": {
      "summ": "0x00000000000000000000000000000000000000000000000000000000000000cc"
    }
  },
  "Signature": "None",
  "Header": null,
  "FunctionId": "00000000"
}

If recompile contract without pubkey pragma, then this issue can not be reproduced. Then both bodies are decoded for those contract.
