Saving event intermittently throws 500 error
Overview
Saving an event intermittently results in a hang with:
- Greyed out tab contents
- Spinning cursor
- Error in the browser console: "VM6153:1 POST https://dmaster.demo.civicrm.org/civicrm/ajax/inline?class_name=CRM_UF_Form_Inline_PreviewById&id=14&snippet=json&crmAngularModules=crmApp,crmProfileUtils,crmResource,crmUi,crmUtil,ngRoute,ngSanitize,volunteer 500 (Internal Server Error)"
Upon a page reload following a hang, the following popup is displayed:
We can't load the requested web page. This page requires cookies to be enabled in your browser settings. Please check this setting and enable cookies (if they are not enabled). Then try again. If this error persists, contact the site administrator for assistance.<br /><br />Site Administrators: This error may indicate that users are accessing this page using a domain or URL other than the configured Base URL. EXAMPLE: Base URL is http://example.org, but some users are accessing the page via http://www.example.org or a domain alias like http://myotherexample.org.<br /><br />Error type: Could not find a valid session key.
Problem confirmed on https://dmaster.demo.civicrm.org.
Reproduction steps
- Go to https://dmaster.demo.civicrm.org
- Click Events | Manage Events.
- Rain-forest Cup Youth Soccer Tournament: Click Configure | Online Registration.
- Click Save
Current behaviour
About 50% of the time it will hang as described above. Oddly, the failures do not seem to be randomly distributed. It seems that it will tend to fail consistently for several minutes, and then to save successfully for several minutes. Or maybe I'm doing something subtly different that I have not noticed which makes the problem appear.
Problem has been observed upon saving various tabs (Info and Settings, Event Location, Online Registration)
Problem has not been observed upon clicking Save and Done.
Stress Testing
After a page load and successful save, it appears that every subsequent save will be successful. To stress test, therefore, the following sequence must be repeated:
- Refresh page
- Save
GET/POST Requests
When saving the Online Registration tab, the following sequence is observed in the browser's Network tab for a successful save:
- POST https://dmaster.demo.civicrm.org/civicrm/event/manage/registration?action=update&id=3&component=event&qfKey=CRMEventFormManageEventRegistrationlkkd3ym1nsgogsggw8scokgo8kw04w0cw00wsg8csgwkc4gcw_4298&snippet=json&crmAngularModules=crmApp,crmProfileUtils,crmResource,crmUi,crmUtil,ngRoute,ngSanitize,volunteer
- GET https://dmaster.demo.civicrm.org/civicrm/event/manage/registration?reset=1&action=update&id=3&component=event&qfKey=CRMEventFormManageEventRegistrationlkkd3ym1nsgogsggw8scokgo8kw04w0cw00wsg8csgwkc4gcw_4298&snippet=json&crmAngularModules=crmApp,crmProfileUtils,crmResource,crmUi,crmUtil,ngRoute,ngSanitize,volunteer
- GET https://dmaster.demo.civicrm.org/civicrm/ajax/inline?class_name=CRM_UF_Form_Inline_PreviewById&id=12&snippet=json&crmAngularModules=crmApp,crmProfileUtils,crmResource,crmUi,crmUtil,ngRoute,ngSanitize,volunteer
When the save fails, however, only the third request is observed, and it throws a 500 error.
