Error: An unexpected 'StartArray' node was found when reading from the JSON reader.

We're getting an error on save of a record in the unified client. The error only occurs when making a change to a multi-select picklist field.

The error just started occurring; we haven't made any recent code changes.

We tried removing the custom JavaScript code on the form but the error stills appears.

We cleared the browser cache. The error is occurring for three out of four users. All users are using the same version of Chrome.

It looks like built-in code on the form is presenting the multi-select options as a JSON array (e.g., [10000001,10000002]) but the code is likely expecting just a comma-delimited list of values. That is probably why the error indicates "unexpected 'StartArray'".

Any ideas for working around this?

Thanks!
