Storing data in collection via backend jsw (wix-data insert).

[bwprado]

You are dealing with Promises using both async/await and code and the .then() method. You should only use one or the other.

Try this at the end:

...
try {
  return await wixData.insert('Tasks', toInsert, options)
} catch (error) {
  console.error(error)
  throw error
}
...
