This is for iOS. I'm using in-app purchases in my React Native app, and I use the following code:

     IAP.initConnection()
        .catch((e) => {   
          throwError(`Error connecting to the in-app purchase store: ${e}`)})
        .then(async () => {
          await IAP.getPurchaseHistory()
            .catch(e => throwError(`Errors fetching purchase history: ${e}`))
            .then(async (receipt) => {
              validate(receipt)
            });
        });

If I'm not already signed into a sandbox account Apple ID, calling IAP.getPurchaseHistory prompts the user to sign in. If I do, then IAP.getPurchaseHistory() always throws an error.

Has anyone encountered this?
