GitHub user dejan032 opened a pull request: https://github.com/apache/guacamole-server/pull/207 GUACAMOLE-673: Create automatically needed directory for file transfer. Automatically create transfer folder in guacd file system when user is logged in to rdp, so that the transfer network drive can be used immediately without needing to open it first one time to start copying things into and out of it. You can merge this pull request into a Git repository by running: $ git pull https://github.com/dejan032/guacamole-server master Alternatively you can review and apply these changes as the patch at: https://github.com/apache/guacamole-server/pull/207.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #207 commit 48974cf79fa629dc63d35665d57cfdc79dd8fda4 Author: Dejan Milovanovic Date: 2018-12-04T07:31:45Z GUACAMOLE-673: Create automatically needed directory for file transfer. ---

That specific message will occur if a custom field type cannot be used:
https://github.com/apache/guacamole-client/blob/fc457c080d813044e30e1f4e8fe855d6a5900259/guacamole/src/main/webapp/app/form/directives/formField.js#L152
That's just a generic "catch", though. If an exception occurs
somewhere within the promise handling (due to something now being
broken in our handling of custom fields?), you could see the same
result, despite the field type being correctly registered. If this is
the case, other things that use custom fields like Duo or TOTP may
also not work as expected. Worth rechecking.

I have a test deployment which uses OpenID against Google - I'll recheck.

Did this error occur in 0.9.14?
If this is breaking things, and did not occur when CAS support was
initially released, I'd suggest a git bisect to narrow down when it
started.

At the time this failure occurs, the user hasn't requested anything - the
stack size is set permanently at build time. This message should be rephrased
such that the nature of the error can be understood by the user running guacd.
