например, я получил ниже сообщение от chromeveloptool:
TypeError: Cannot read property 'getData' of undefined
at ExpenseLineItem.getAttachmentDownloadPath (expenseLineItem.ts:186)
at expenseLineItem.ts:89
at arrayEach (lodash.js:516)
at Function.forEach (lodash.js:9342)
at ExpenseLineItem.populateExpenseLineItem (expenseLineItem.ts:86)

at arrayEach (lodash.js:516)
at Function.forEach (lodash.js:9342)
at Expense.populateExpenseDetail (expense.ts:147)
at em-expense.service.ts:60
так какая строка выполнялась сначала? первая или последняя строка?
