readonly callSC is not working

[veratek]

The problem(s)
Calling purge from deweb SC fails when using station

To Reproduce

  async function handlePurge2() {
    setIsPurging(!isPurging);
    const callScParams:CallSCParams ={
      target: SC?.address || "",
      func: "purge",
      parameter: Uint8Array.from([]),
    }
    try {
     connectedAccount?.callSC(callScParams 
     ).then((res) => {
        res.waitFinalExecution().then((res) => {
          console.log("Final Execution", res)
        })
     })
    } catch (e) {
      console.error("Error while trying to read SC", e);
    }
  }

should see:
json: cannot unmarshal object into Go struct field LedgerUpdate.state_changes.ledger_changes.Update.bytecode of type string

Expected behavior(s)

Return Operation

Any other useful info
This may be happening only because we are changing the bytecode in the purge call
we need to change type string towards type bytes: pkg/node/sendoperation/interfaces.go line 115
