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.

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


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)


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 -w 2 -t 120 --limit-request-line 0

In order to apply changes restart wsgi server:

sudo supervisorctl reload
