Here are some logs from testing:

MintOperationError: Input unit must match output
 status: 400,
   code: 11010,

When sending a swap payload without either no inputs or no outputs (empty list) the mint returns a 11010 (Inputs and outputs not of same unit) instead of the 11002 (transaction not balanced) error. Probably due to the fact that there are no ids in the input/output to determine the unit. Here are some logs from testing: ``` [sqlite3-integration module=WalletService module=RequestRateLimiter] DEBUG: Mint request { method: "POST", endpoint: "http://localhost:3338/v1/swap", requestBody: "{\n \"inputs\": [\n {\n \"id\": \"001b6c716bf42c7e\",\n \"amount\": 32,\n \"secret\": \"c51d06255a492d1b8d5a35039f5ad4bf0b370cda130502094820c44d87e5e6af\",\n \"C\": \"02281f64f578317808dde78c199ec68b585fba15d0dc90a9b91fc7d3e0eb4c4030\",\n \"mintUrl\": \"http://localhost:3338\",\n \"state\": \"inflight\",\n \"createdByOperationId\": \"9e9skBsss9nnx-zfqkEoyw\"\n },\n {\n \"id\": \"001b6c716bf42c7e\",\n \"amount\": 8,\n \"secret\": \"94a80d42c9d16563cb5de5f6c4e0718f6dad209971634e0b086f518e0d5b3a0e\",\n \"C\": \"02fe89a5b1beb664b4ba48b3668c893734dba1d6bcf6391edad2b016b499516de9\",\n \"mintUrl\": \"http://localhost:3338\",\n \"state\": \"inflight\",\n \"createdByOperationId\": \"9e9skBsss9nnx-zfqkEoyw\"\n }\n ],\n \"outputs\": []\n}", } [sqlite3-integration module=WalletService module=RequestRateLimiter] DEBUG: Mint response error { endpoint: "http://localhost:3338/v1/swap", status: 400, errorData: "{\n \"code\": 11010,\n \"detail\": \"Input unit must match output\"\n}", } 793 | status: response.status, 794 | errorData: JSON.stringify(errorData, null, 2) 795 | }); 796 | if (response.status === 400 && errorData && typeof errorData.code === "number" && typeof errorData.detail === "string") { 797 | const { code, detail } = errorData; 798 | throw new MintOperationError(code, detail); ^ MintOperationError: Input unit must match output status: 400, code: 11010, ```
