UserWarning:“会话”cookie太大：值为14773751字节，但标头需要额外的26字节

Question

我需要在flask会话中存储数据帧，我执行以下操作：

session['pd'] = pd.to_dict()

我有一个错误：

UserWarning: The 'session' cookie is too large: the value was 14773751 bytes but the header required 26 extra bytes. The final size was 14773777 bytes but the limit is 4093 bytes. Browsers may silently ignore cookies larger than this.
samesite=samesite,

我加上这一行：

app.config["SESSION_TYPE"] = "filesystem"

但一切都没有改变

我怎样才能解决这个问题
