v1.5.4 IPN error logs

When I used Zencart 1.5.4 and installed Paypal express checkout(debug), there are IPN errors as soon as someone place order in my Ebay account.
The system sent me 18 IPN error emails for each transaction. I posted some of them below:

#1
IPN PROCESSING INITIATED. 
*** Originating IP: 173.0.81.1  notify.paypal.com
*** Browser/User Agent: PayPal IPN ( [url]https://www.paypal.com/ipn[/url] )


#2
IPN ERROR :: Could not find stored session {} in DB; thus cannot validate or re-create session as a transaction awaiting PayPal Website Payments Standard confirmation initiated by this store. Might be an Express Checkout or eBay transaction or some other action that triggers PayPal IPN notifications.

#3
IPN ERROR :: No saved Website Payments Standard session data available. Must be an Express Checkout or Direct Pay transaction.
Could be a test notification, or the incoming IPN notification is not actually a bonafide PayPal transaction.
NOTE: It is likely that all the following log content is meaningless or irrelevant.

#4
Breakpoint: 0 - Initializing debugging.

#5
Breakpoint: Flag Status:
isECtransaction = 0
isDPtransaction = 0

...


#9
CURL response: VERIFIED

#10
IPN INFO (cl) - Confirmation/Validation response VERIFIED

#11
Breakpoint: 1 - Collected data from PayPal notification

#12
Breakpoint: 2 - Validated transaction components

#13
Breakpoint: 3 - Communication method verified

#14
IPN NOTICE :: Could not find matched txn_id record in DB. Therefore is new to us.

#15
Breakpoint: 4 - Details:  txn_type=unique    ordersID = 0  IPN_id=0

   Relevant data from POST:
     txn_type = unique
     parent_txn_id = None
     txn_id = xxx

#16
IPN ERROR :: Could not find stored session {} in DB; thus cannot validate or re-create session as a transaction awaiting PayPal Website Payments Standard confirmation initiated by this store. Might be an Express Checkout or eBay transaction or some other action that triggers PayPal IPN notifications.

#17
IPN ERROR :: No pending Website Payments Standard session data available.  Might be a duplicate transaction already entered via PDT.

#18
NOTICE: IPN Processing Aborted due to missing matching transaction data, as per earlier debug message. Perhaps this transaction was already entered via PDT? Thus there is no need to process this incoming IPN notification.

Could someone help to fix it? Thanks very much in advance!

I think that this says it all - ebay and PPexpress must not be compatible

I don't think that it's either an issue or incompatibility. When a purchase is made on your eBay account, PayPal is simply sending your store a notification of that purchase via IPN.

I've seen that, too, when someone sends me money (via the PayPal send_money interface). There's an IPN log present in the logs folder to indicate that the payment was made but, since it's not tied to an order there's nothing for Zen Cart to do.

Thanks for your response!

Actually, I don't have such issue when I used Zen1.5.1.

I also think it is just a notification that someone purchasing in my Ebay account. But it is quite annoyed! I have to remove 18 IPN notification emails for each Ebay transaction. Is it possible to fix this issue?

Thank you very much!

Simple: Turn off PayPal Debug Logging in your ZC PayPal module.

Thank you! That's a way to stop receiving IPN logs message but I'm afraid it will also block the true error warning in future.
Is it a problem of zencart 1.5.4 or just my account problem as I do not have this issue when using zen 1.5.1? Could it be fixed other than turn off it?

Thanks~!

It's how PayPal works when you use PayPal Payments Standard.

Both eBay and PayPal transactions will send an IPN to your store. And the Payments Standard module REQUIRES that IPN in order to record the sale in your store.

Zen Cart correctly does nothing with the eBay notices, but if you've got IPN logging enabled you'll get those logs.

If you use PayPal Express Checkout instead of PayPal Standard, you won't get those IPN logs.

Thanks for your detailed explanation!

Actually, I only use the Paypal express checkout after fresh Zencart 1.5.4 installation. But don't know why I still get those IPN logs

You have set the debug mode for email & logs
Set it to off

Will it block ALL IPN notifications (i.e. not only those transaction logs and also real error notification)?

Thanks

Yes I am afraid that one can not have it both ways
Either all logs or no logs
