Field format error: Request is too large to process

Hi,

I am also receiving this exact problem, do you know or have seen anything that you've tried to get this work?

thanks,

I am having the same issue on a site that has been up and running for a while.
I found only a few other mentions online for this problem and all of the recent.
Even though this issue is old, the latest comment is also recent,
so the most probable answer seems to be that paypal altered
something in their API in the last month and only large orders
with multiple line items get this issue so it may not be very common.

Sorry to not provide an answer, but we'll continue looking into this,
maybe contact paypal if needed.

I too am having this problem. I have a stuck order with 27 line items.

Did some additional research and discovered that the number of line items isn't what triggers the error, it's the total size of the payload being sent to PayPal. I got to thinking this when @zooter626 reported that 10 items triggered the error but I could get to 15 before I triggered the error. I found this Stack Overflow (http://stackoverflow.com/questions/39480168/field-format-error-request-i...) issue that suggested that the CURLOPT_POSTFIELDS is too long for what PayPal will accept.

I can't find anything in PayPal's documentation that indicates any sort of payload limitation.

The attached patch adds a checkbox to the Payment Method page that allows us to omit the itemized list (line items).

A site I work on was having this same issue, and after applying the patch above, a LOT of the errors stopped. However some still do come through. Upon inspecting the logs, it appears that the excess information is still being sent to PayPal.

Here's two associated logs, with any personal info removed:

@tophneal I don't think the patch applied for you. Can you try this re-roll?

It looks like the L_NAME[] query string generated for the CURL request becomes too long for PayPal to accept in these situations.

@andyg5000

Thank you for the patch! I just rolled it, but of course I'll have to wait for a large order to be processed. I'll report back if there are still issues.

Great, just be sure to update the payment settings to omit them too, if you haven't already :)
