The origin of the crash has ben found by @joshuafontany in an other thread on tiddlytalk, that I paste here for any reader to know it:
==== You have run into a bug in 5.1.23 and earlier that would crash the server trying to write a tiddler with no text field. This happens rarely, but most often when an $action-setfield widget sets a NON-text field on a non-existent tiddler (this creating it without a text field). The button in the plugin sets a temp tiddler’s NON-text fields, and that is when the crash is happening. I would recommend using the pre-release on node. ==== Le lundi 27 septembre 2021 à 19:37:45 UTC+2, Jean-Pierre Rivière a écrit : > Hi Matt.
