unable to query biblio in bulk anymore -- "Error: Maximum response size reached"

Post by jalipert » Fri Mar 11, 2022 10:01 pm

Hi Vesna and OPS team,

We used to be able to query biblio data in bulk for up to 100 documents at once using the https://ops.epo.org/3.2/rest-services/p ... doc/biblio endpoint. There seems to be a new limitation preventing this from working correctly.

Even querying 10 documents at once can produce an "Error: Maximum response size reached" response.

To reproduce, try querying the following documents in batch:
US10617412
US10874391
US10856868
US10835249
US10687806
US10687812
US10743849
US10548504
US10828032
US10973516

Any ideas? We have petitioned in the past to have the size of the biblio response reduced by optionally eliminating the list of citations, which might help correct this issue. Maybe that request can be reconsidered to help solve this? Otherwise, can the Maximum response size error be removed or the allowed response size increased in the meantime?

Best,
Joe

HI

Thanks for reporting this, this shouldn't be the case, bulk biblio option should be unchanged. Did you try with POST as well? Or with other list of numbers? Sometimes can be one single record that causes entire query to fail.

I have asked developers to have a look too but would be great if you reply to these additional questions

Hi Vesna,

Yes we are using POST requests. It is reproducible with the list of 10 docs I sent in my original post. Here is a screen capture of the Postman tool showing the "Error: Maximum response size reached" response.

Thanks,

Hi,

The limitations have not changed but it seems that in the list of those US doc's there is at least one that causes error. We asked documentation colleagues to have a look.
