<p>router.get('/',(req,res)=&gt;{...})에서요</p>
<div style="color: #d4d4d4; background-color: #1e1e1e; font-family: Consolas, 'Courier New', monospace; font-size: 14px; line-height: 19px; white-space: pre;">
<div>&nbsp;&nbsp;<span style="color: #6a9955;">//&nbsp;user에&nbsp;패스워드정보도&nbsp;들어가있어서&nbsp;없애줘야한다</span></div>
<div>&nbsp;&nbsp;<span style="color: #569cd6;">const</span>&nbsp;<span style="color: #9cdcfe;">user</span>&nbsp;=&nbsp;<span style="color: #4ec9b0;">Object</span>.<span style="color: #dcdcaa;">assign</span>({},&nbsp;<span style="color: #9cdcfe;">req</span>.<span style="color: #9cdcfe;">user</span>.<span style="color: #dcdcaa;">toJSON</span>();)</div>
<div>이렇게 toJSON해야 circular error가 안나는데요</div>
<div>req.user는 json이아닌가요 왜 해야하죠?</div>
<div>sequelize에서리턴되는값은 잡객체라서 toJSON()해야한다고하셧는데</div>
<div>req.user도 잡객체인가요?</div>
</div>

<p>네 req.user이 sequelize에서 리턴된 값입니다(deserializeUser보시면 됩니다)</p>
