#<NoMethodError: undefined method `at_xpath' for nil:NilClass> about spreedly-gem HOT 14 CLOSED

I'd be curious if the error ever happens without zeus. Just trying to eliminate possibilities.

from spreedly-gem.

Yes I'm hitting the same error without zeus. Any ideas?

Looks like it's happening when the gateway_transaction is attempting to initialize. I'd love to see the response body when the exception happens. Looks like it's having difficulty finding one of the fields. I wonder which one it is.

from spreedly-gem.

@duff, i'm having the same issue. Initialization fails. The chunk of response that triggers error:

Thoughts?

Hi @sosedoff,

Looks like the message there says:

 <message key="messages.cannot_use_redacted_gateway">Unable to use a gateway because it's been redacted.</message>

from spreedly-gem.

Looks like the gateway you're trying to use to do the purchase has been redacted.

from spreedly-gem.

@duff, i know, this is intended. I was testing purchase on redacted gateway. The problem is with command
that returns transactions history: env.list_transactions. It breaks.

from spreedly-gem.

Sorry @sosedoff,

I think I'm missing some context. How does it break? What error are you getting?

from spreedly-gem.

Im getting error when calling env.list_transactions. Backtrace:

Then i monkey-patched connection class to get response output before it gets processed by the library.
I provided response body in my previous message. Sorry, i was not very clear in describing the issue.

from spreedly-gem.

Coolo. If you could share the transaction's token, I should be able to replicate it here and see if I can put together a fix.

from spreedly-gem.

Ok, let me lookup the exact transaction token.

from spreedly-gem.

Here is the transaction token that triggers error on both find_transaction and list_transactions:

D23rZq2muGCYQUMVGu1a2qcG9PK

from spreedly-gem.

Just pushed a new version of the gem with the fix.

Thanks for the help in narrowing it down! This was the fix in case you're curious: d58a51e

version 2.0.5 of the gem includes the fix.

from spreedly-gem.

Thanks for the quick fix!
