Getting "Error 500" with no error message when logging in

[elgiad007]

Hello,

I installed the plugin, generated a hash, and added the user information to my metadata.json file. Whenever I enter my account information and click the "Log In" button I am taken to the standard "Error 500" page with no information in the red box to indicate what the error is. In the Datasette output, all I see is this:

INFO: 192.168.1.1:4240 - "POST /-/login HTTP/1.1" 500 Internal Server Error

I am running Datasette on a Windows 10 desktop. Here is the script that launches Datasette (some things replaced to avoid exposure):

@echo off
set PASSWORD_HASH_replacedusername="<hash generated by plugin and surrounded by double quotes>"
datasette <path to db file> --metadata metadata.json -h 0.0.0.0 --ssl-keyfile <path to key file> --ssl-certfile <path to cert file> >> datasette.log 2>&1

I did try surrounding the hash value in the above script with single-quotes instead of double-quotes, to no effect.

Here is the output of "/-/plugins":
