client.Balances.GetPrimaryTransactionsList() Eventually Throws Error

[MarcoWel]

Describe the bug The following code throws an error after about 4000 balance items:

fromId := ""
for {
      opts := mollie.BalanceTransactionsListOptions{From: fromId, Limit: 250}
      _, items, err := client.Balances.GetPrimaryTransactionsList(context.Background(), &opts)
      if err != nil {
          log.Fatalf("Failed to retrieve balances: %v", err)
      }
      if fromId = GetNextId(items.Links); fromId == "" {
        break
      }
}

Error: Failed to retrieve balances: json: cannot unmarshal array into Go struct field BalanceTransaction._embedded.balance_transactions.context of type mollie.ContextValues exit status 1

Additional context https://github.com/VictorAvelar/mollie-api-go/blob/master/mollie/balances.go

type (
    // TransactionType specifies the reason for the movement.
    TransactionType string
    // ContextValue represents a relevant value in the system
    // associated with a BalanceTransaction.
    ContextValue string
)

// ...

// ContextValues is a map of TransactionType to ContextValue.
type ContextValues map[TransactionType]ContextValue

Narrowed down the response causing the issue. First item looks good, second item is causing the error with "context": []:

This one will be closed as soon as #328 is merged, I found a different approach which covers more edge cases than the original proposed solution.

Thanks for raising this issue and sorry if it took a while to be resolved.
