Local files error?

[jeremy-schweitzer]

I've been testing this plugin because I think it's exactly what we need, but I'm running into an issue. I think it's a bug, but it's always possible user error. I just don't see an obvious problem.

I've setup the plugin on two sites and enabled it. I can search the remote site for courses, but when I click on a course title to import it. I've tested on 3.1, 3.2, and 3.3dev. I get the following exception on each version:

Unknown exception related to local files (Can not fetch file form URL)

Error code: storedfileproblem

Stack trace:

Output buffer:

@jeremy-schweitzer thanks for the report. If I had to hazard a guess, the plugin is getting a bad response from the web service. I need to add better troubleshooting; could you try adding this statement (or something similar) immediately after line 69 in index.php and report back what's in the log:

error_log(print_r($resp, true));

Hi, I have the same error, I do print_r ($ resp) on line 69.
answer: stdClass Object ( [exception] => backup_controller_exception [errorcode] => backup_check_user_not_exists [message] => error/backup_check_user_not_exists )
Has anyone already fixed it?

Hi all,
I just installed this plugin and encountered the same error. Has one of you already found a solution?

Hola, ese error fue hace mucho, si recuerdo bien, es porque un moodle no puede verse con el otro, o acceder a la carpeta del otro.
Si quieres cúentame que necesitas, quizá te pueda ayudar

Hi,
I Google-translated your reply. My Spanish is a little bit rusted :-)

But this shouldn't be a problem if I call the backup function via web services with the right user (rights), should it?

[danisierravergel]

The backup is created in a directory outside of www, so you can not access it.
Postscript: my English is bad

Steps to reproduce

On the provider

• create an user for webservice with username 'wsaccount' and configure WS as described in README.md

On the client

1. Log in as an administrator on the client. (Important : username must not be 'wsaccount' for example 'foo')
2. Configure the client to use the 'wsaccount' token.
3. Try to restore a remote course you should see the error appear.

Explanation

Client send current user's username (foo) to the provider and try to use it to do the backup instead of wsaccount user. But this account may be inexistant or do not have required permission on the provider.

Fix

See PR #13 it remove username param to directly use $USER which is the WS user (so 'wsaccount')

[behoof]

When I add on the client the same username and I log in with that username: the error is gone.
So the username on the client and the provider must be equal?

[ak4t0sh]

Exactly, username on client and provider must be equal. That's what #13 intend to fix.
