Dear David,

First of all, ignore my previous request for info on how to debug 
failed synchronisation operations: I've seen that you create an 
*org-caldav-debug* buffer and I've seen that the errors are 404 
errors.  Trying again has resolved those failed synchronisations. 

I am unable to get entries any entries created in Google's 
calendar to appear in my org inbox file, whether old or new.  The 
output from org-caldav indicates nothing has been done yet the ics 
events file from Google does have the relevant entries. 

Further, I seem to have run into strange problem: every time I 
start a new sync operation, I get the following error:

,---- | Debugger entered--Lisp error: (error "Could not find UID 
emacs20726839125514526.")  |   signal(error ("Could not find UID 
emacs20726839125514526."))  |   error("Could not find UID %s." 
"emacs20726839125514526") |   (progn (error "Could not find UID

command-execute(org-caldav-sync record) | 
execute-extended-command(nil "org-caldav-sync") | 
call-interactively(execute-extended-command nil nil) `---- 

I've truncated the lines for posting but I'm happy to send you the 
full output from the debug trace.

I cannot find the UID anywhere in my files.

However, if I try org-caldav-sync again, it asks whether I want to 
resume the interrupted sync operation and it works.  This 
behaviour is consistent. 

I wonder whether the two things are related?

Thanks,
eric
