TypeError: record.getCellValue is not a function or its return value is not iterable

[confused_person]

Hi,

I'm getting this error when trying to append to a linked field. The code in question is:

ModelRange.updateRecordAsync(record, {'Models List': [...record.getCellValue('Models List'),{id : BMRecord[0]}]});

I'm pretty sure that 'record' is indeed a record object, as it's obtained from 

let query = await ModelRange.selectRecordsAsync();
let record = query.getRecord(another[0]);

where another[0] is a record ID. Let me know if the rest of my code is needed to diagnose the error, although I can imagine that I'm missing something obvious.

Thank you!

I found a workaround - all I needed to do was add all my linked records at once in an array.
