grid.import.apply was given something it cannot import: pass delimited text, a preview from grid.import.preview, or an array of record objects.

Warnings reference › import.apply.input

Identifier

import.apply.input

Raised by

The grid (core)

Since

1.38.0

What happened

The input is none of the three things apply takes, so nothing was imported and an empty record list was returned. A File or a Blob arrives here: both have to be read to text or bytes first.

The fix

Pass delimited text, a preview object, or an array of records.

The smallest fix

grid.import.apply(await file.text());
