| Situation | Error code | Description | Error code |
|---|---|---|---|
| Item scale cannot be converted to target scale | -32602 | The specified scale cannot be used | rpc.params.scale.invalid |
| Bus send message operation timeout | -32602 | Bus request timeout | |
| Bus incorrect message size (more then 100K) | -32602 | Bus message is too long | |
| Bus data transfer another error | -32602 | Bus internal error |
Note: There are problems with the spread bus data transfer if input data amount > 100K. If the data amount for set.item.value operation >= 50К we will have in internal broadcasts hub.item.updated amount ~ 100K (because added valueFormatted parameter). The solution to fix this and similar issues with big data was added input bus data handling. If bus input data more than 100K then instead of bus data transfer will be returned – error. This handling is implemented for web-socket API Lua interface and external controller API.
