Session error (I deleted all data and now is giving this error

Moralis General
#1

  80 | const query = new Moralis.Query(Cuser);
  81 | query.equalTo("email1", em1);

I did this before, I don’t know how the session token works or the role object either, but when I have to delete data because server I am using for testing is full, this error happens each time. How can I understand / prevent this ?

You deleted the session table from the server?
