CodePudding user response：

data.tenderPlan.tenderPlan.paymentGroups[0].allocations is an empty array, so there is no third element in it which you tried to access with .allocations[2].

Read the JSON carefully, ideally in some sort of beautifier - there are many of them available online.

CodePudding user response：

data.tenderPlan.tenderPlan.paymentGroups[0].allocations is empty array in your object.

You can see your all paymentGroups with data.tenderPlan.tenderPlan.paymentGroups to make sure.

data.tenderPlan.tenderPlan.paymentGroups[0].allocations has 0, data.tenderPlan.tenderPlan.paymentGroups[1].allocations has 1 and data.tenderPlan.tenderPlan.paymentGroups[2].allocations has 1 data.
