Script error when setting columns property of a Table element

[gjsjohnmurray]

bundled.js:2511 Uncaught TypeError: e.filter is not a function
    at Xi._calcColWidthPercentages (bundled.js:2511:3619)
    at Xi._initDefaultColumnSizes (bundled.js:2511:4213)
    at set columns (bundled.js:2511:1684)
    at Xi.set [as columns] (bundled.js:1:2407)

_calcColWidthPercentages @ bundled.js:2511
_initDefaultColumnSizes @ bundled.js:2511
set columns @ bundled.js:2511

(anonymous) @ loaderScript.js:48

In this case my table had 3 columns and my script was doing this:

tblColumns.columns = '["auto", "auto", "auto"]';

I am using v2.3.1

Thanks, I'll take a look at it later.
