This is actually an exchange issue! Very hard to reproduce, since only some upload contents seem to cause this behavior. Notably, a form with a field that contains large random base32-crockford encoded data *doesn't* trigger this behavior. What does trigger it is a form upload with multiple JSON fields that each have some structure and a large-ish base64 string. Here's a reproducer: $ taler-harness run-integrationtests kyc-form-compression |

Leads to the following error log in the exchange: 2025-06-24T11:02:57.880899+0200 taler-exchange-httpd-3905977(6JYCXE9RF0HP289SFKK8RHPT68) INFO Handling request (POST) for URL '/kyc-upload/Q61H7346DZ8DA93886MGW3B1NPZGNAF3FZKKE5QDPF4SQ2TH8EWG-0-1' 2025-06-24T11:02:57.880926+0200 taler-exchange-httpd-3905977(6JYCXE9RF0HP289SFKK8RHPT68) WARNING External protocol violation detected at ../src/lib/mhd/mhd_upload.c:191. |
|
|
Note that the POST body is *not* malformed, taking it manually and piping it through "openssl zlib -d" produces the correct output. |

|
Fix committed to master branch. |
|
|
Actual fix is in libgnunetmhd. |
