Add doc in sub-table via action

[webwurm]

I can't figure out how to add a document in a sub-table of the current row in an action-script.
This is what I came up with to add an entry to the sub-table "logHistory" in the current row:

`const action:Action = async ({row,ref,db,storage,auth,actionParams,user}) => {

const newEntry = {
finishedTask: "Test!",
timestamp: Date.now,
};

ref.collection('logHistory').add(newEntry);
}`

Sadly I get the error:
Cannot read properties of undefined (reading 'success')

Can somebody point me in the right direction please. Thanks!

hi @webwurm , actionScripts has an expectation of a returned object
you mainly need to add something like this to the end of your function

return {
success:true,
message:"entry created"
}

Thanks a lot, that works perfectly:

const action:Action = async ({row,ref,db,storage,auth,actionParams,user}) => {

  const newEntry = {
    finishedTask: "Test!",
    timestamp: new Date(),
  };

  ref.collection('logHistory').add(newEntry);

  return {
    success: true,
    message: `Log-Eintrag ${newEntry.finishedTask} erstellt`
  }

}
