Crash ERPNext v11 when acces option "Data export"

When I enter “Data export”, I get to enter the first screen, then when I try to search for Doctypes, the field does not show any doctype, then immediately the ERPNext site can no longer be accessed from the browser.

Data:
ERPNext v11
ERPNext language: Spanish
User in session: administrator
Security permissions: The administrator user has permission to export

HELP PLEASE

Works fine on my test build.

Any error message in the browser’s console?

Please test in language spanish, there the error appears.

I test in this version and crash:

ERPNext: v11.0.3-beta.15 () (staging)
Frappe Framework: v11.0.3-beta.15 () (staging)

I update the version, I can not export yet, when trying to find a datetype it does not show any and then the system hangs up and does not allow to enter

ERPNext: v11.0.3-beta.19 () (staging)
Frappe Framework: v11.0.3-beta.22 () (staging)

Crash:

SOLVED: I have been configuring the supervisor “–limit-request-line 0”, I detail solution:

Added option --limit-request-line 0 into wsgi server startup line.

Config file [/home/erpnext/frappe-bench/config/supervisor.conf]:
line 2> command=/home/erpnext/frappe-bench/env/bin/gunicorn -b 127.0.0.1:8000 -w 2 -t 120 --limit-request-line 0 frappe.app:application

In order to apply changes restart wsgi server:

sudo supervisorctl reload
