Error: Username already exists [403] Meteor -

i have manually created user on meteor app accounts.createuser , have disabled sign ups user. worked until restarted server , started getting error:

error: username exists. [403]

i have accounts.createuser under if (meteor.isserver), suspect created user may issue. thoughts?

you're running accounts.createuser every time run app.

try doing this, create user if there none in collection.

if(meteor.isserver) {     if(!meteor.users.findone()) {          accounts.createuser(....)      } }

Running
