Vault Manager Crashing When Removing Payment Method

[tlynchlaw]

General information SDK/Library version: 4.30.0 Environment: Sandbox iOS Version and Device: iOS 13 on iPhone 11 (actual device) Integration type and version: CocoaPods 1.8.4 Issue description Using vaultmanager to edit saved payment methods. When deleting a method, am getting this error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[2]' *** First throw call stack: (0x18664dc30 0x1863680c8 0x1866a65f4 0x1866b0414 0x1865345f0 0x186525e9c 0x102ab0e14 0x102aafa90 0x102ab0c00 0x1898aaffc 0x1898bb8dc 0x186a1dc60 0x18691f7e8 0x186a1ffbc 0x18691f464 0x186a209e8 0x186a204a8 0x105ad9a48 0x105acb2a8 0x105ace084 0x105acd468 0x105adcaac 0x105add418 0x18635aa60 0x186360c78) libc++abi.dylib: terminating with uncaught exception of type NSException

vaultmanager working fine on the same phone in a different app we built.

I'm unable to recreate the issue. Could you put in a symbolic breakpoint for the NSInvalidArgumentException to track this down to a line number?

[tlynchlaw]

Here's what I got:

libsystem_kernel.dylib`__pthread_kill:

0x1a6edaef4 <+0>:  mov    x16, #0x148

0x1a6edaef8 <+4>:  svc    #0x80

-> 0x1a6edaefc <+8>: b.lo 0x1a6edaf18 ; <+36>

0x1a6edaf00 <+12>: stp    x29, x30, [sp, #-0x10]!

0x1a6edaf04 <+16>: mov    x29, sp

0x1a6edaf08 <+20>: bl     0x1a6eb955c               ; cerror_nocancel

0x1a6edaf0c <+24>: mov    sp, x29

0x1a6edaf10 <+28>: ldp    x29, x30, [sp], #0x10

Hi @tlynchlaw. This still isn't enough information to replicate your issue.

You can also try setting an exception breakpoint to get some more information on the state of the app before it crashes, if potentially the symbolic breakpoint isn't doing what you need.

[tlynchlaw]

Here's what I get the exception breakpoint: line 181 of BTGraphQLHTTP

/// Walks through the input path recursively and adds field errors to a mutable array

• (void)addErrorForInputPath:(NSArray <NSString > )inputPath withGraphQLError:(NSDictionary )errorJSON toArray:(NSMutableArray <NSDictionary > )errors { NSString field = [inputPath firstObject];

  if (inputPath.count == 1) { [errors addObject:@{ @"field": field, @"message": errorJSON[@"message"], @"code": errorJSON[@"extensions"][@"legacyCode"] }]; return; }

Then printing the various objects, I get field is singleUseTokenId, and error JSON[@"message"] is Payment method must belong to current customer and errorJSON[@"extensions"] is

{ errorClass = VALIDATION; errorType = "user_error"; inputPath = ( input, singleUseTokenId ); }

Since I'm using the sandbox, could it be there are too many fake users with the 4111 Visa card? I am not having the problem with a production version of another app (which, BTW, shares this braintree account).

UPDATE: I just added a JCB card, which no test account has. Then deleted it and it still crashed.

Are you sure that the customerId you are using to create the clientToken that you are using matches that of the one used to generate the payment method nonce you used to vault the payment?

[tlynchlaw]

We believe the answer is yes. If it wasn’t the same it shouldn’t show the large icons in the drop in.

We turned on production and it works as expected in production. But sandbox for both iOS and Android fails. iOS crashes and Android shows a message that the payment method can not be updated at this time.

@tlynchlaw Are you still seeing this problem in sandbox? If not, I'll close this issue.

[tlynchlaw]

It's been awhile. We went to production so I don't know if it still happens.

I'm going to close this issue then, but please let us know if you run into the problem again.
