Null exception when do a payment with multiple MID by JWT Authentication Type

[non-nattawut]

Step to reproduce :

1. after do all setup for JWT do a payment with MID-A, payment working fine
2. but after switch MID to MID-B and do a second payment (that not associate with first payment) will get error like above picture
3. then I will get Authorization bearer token = null so I cannot do a second payment

cause :

when I drive through library code and I found that AuthenticationSdk 0.0.34
in Cache.class
Method getMerchantP12KeysFromCache()
this line Identity p12Keys = (Identity)cacheP12.get(this.merchantConfig.getMerchantID());
return NULL because MID-B not contain in cacheP12

so next line call p12Keys.getLastModifiedDate() will get NULL exception

My Interim solution :

I use Cache.cacheP12.clear(); to clear cache everytime I create new payment

What I want to ask is, is this intend to be like this? because my use case need to use multiple MID

@Rohan-u

As I mention in interim solution section you can use this line of code to clear the cache before do any transactions like payment, void, etc.

Cache.cacheP12.clear();

I did not sure will it has problem in many thread environment but for now, I tested it on the server that implement multithread it work fine.

I guess it might be different issue than mine but, here is my working code

private ApiClient getApiClient(String mid) throws ConfigException {
Cache.cacheP12.clear();
Properties merchantProp = config.getMerchantDetails(mid);
ApiClient apiClient = new ApiClient();
apiClient.merchantConfig = new MerchantConfig(merchantProp);
return apiClient;
}

PaymentsApi apiInstance = new PaymentsApi(getApiClient("merchantId"));
PtsV2PaymentsPost201Response paymentsResponse = apiInstance.createPayment(requestObject);
