Cannot initialize entity translation path variables (invalid path scheme).

Same problem here, but I had to clear the cache using the UI since I was receiving errors using drush cc.

I am also not able to update the dB using either drush updb or the UI:
The following updates returned messages

entity_translation module

Update #7002
Failed: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'module' cannot be null: INSERT INTO {role_permission} (rid, permission, module) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array ( [:db_insert_placeholder_0] => 2 [:db_insert_placeholder_1] => edit node original values [:db_insert_placeholder_2] => ) in user_role_grant_permissions() (line 3054 of /modules/user/user.module).

EDIT: the dev version fixed the above dB update issue.

This should fix the OP's issue.

Hm, patches need to go against -dev.

#2: cache-clear-update-1833496-3.patch queued for re-testing.

I tested this multiple times and I was not able to reproduce it. I think it's probably caused by an interrupted update process since we have a gobal cache clear at the end of a regular update process:

http://drupalcode.org/project/drupal.git/blob/refs/heads/7.x:/includes/u...

For this reason I think the patch in #2 is useless and I'd like to mark this as a duplicate of #1829980: Upgrade to Beta1 results in "Integrity constraint violation: 1048 Column 'module' cannot be null".

I repeatedly tested the upgrade path between alpha2 and the latest dev without having any issue. Please confirm this is the case also for you ASAP, as I wish to release beta2 very soon.

After further testing I was able to see this by performing the update via drush. Overall I still think this is not ET's business but I guess the attached patch will save us some headache. I moved the fix to update 7004 since people at 7004 right now don't need it. And I don't want to force people on beta1 to perform a db update when moving to beta2.

Benedikt?

Yes, fine by me. Committed and pushed. :)

Hi all,

I appreciate this thread is a bit old, but I'm stuck on 7.x-1.0-alpha2 and keep getting the following error when trying to upgrade:

WD php: Exception: Cannot initialize entity translation path variables (invalid path scheme). in EntityTranslationDefaultHandler->initPathVariables() (line 1411 of   [error] /var/www/...../sites/all/modules/contrib/entity_translation/includes/translation.handler.inc).

I've google and searched the forums but still can't work out how to move forwards with this.

I'm testing on a development site, but need to be quite confident that the upgrade is going to work before I upgrade a large live site which has a lot of entity translations in pace.

Currently on Drupal 7.17.

Any pointers would be much appreciated.

Many thanks,
:wq

Try clearing all caches and running the upgrade again.

Hi,

Thanks #ianmthomasuk and #plach for help so far.

My existing version is 7.x-1.0-alpha2 and I'm trying to upgrade to 7.x-1.0-beta2. I've tried clearing caches, and running database updates first, but no luck.

See the following:

Editing to add that a couple of the lines below seem to look fine in the message source but are a bit out of order in the code preview. Hope it makes sense!:.

Try to perform the update from the GUI, drush was to reported to have some trouble.

Hi,

Thanks plach, I downloaded beta2 and then ran update.php as the administrator via the GUI. I got the following exception thrown:

Error message

Exception: Cannot initialize entity translation path variables (invalid path scheme). in EntityTranslationDefaultHandler->initPathVariables() (line 1411 of /var/www/uk.co.dgfsolutions.office.sil/sites/all/modules/contrib/entity_translation/includes/translation.handler.inc).
The website encountered an unexpected error. Please try again later.

Now, when I try and access the site I just get the following error:

The website encountered an unexpected error. Please try again later.

Clearing the cash I now get:

gregf$ drush cc
WD php: Exception: Cannot initialize entity translation path variables (invalid path scheme). in EntityTranslationDefaultHandler->initPathVariables() (line 1411 of   [error]
/var/www/uk.co.dgfsolutions.office.sil/sites/all/modules/contrib/entity_translation/includes/translation.handler.inc).
Drush command terminated abnormally due to an unrecoverable error.                                                                                                    [error]

So unfortunately I now can't get onto the site at all. Any suggestions on how I can proceed without referring to a backup?

Many thanks,
:wq

Comment line 1411 in translation.handler.inc and perform a drush cc. Then you should get only some notices. Try to ensure all the db updates have run, if so try the latest dev, otherwise try to complete the upgrade and then restore the commented line.

Hope this helps.

Hi,

Apologies I haven't been able to look at this again between Friday and now.

Thanks plach, commenting out line 1411 did the trick for me. For anyone else who has this same issue, here's what I did:

1. Manually downloaded latest version of entity_translation.
2. Edited entity_translation/includes/translation.handler.inc, commenting out line 1411. The function then looked like this:

  /**
   * Initializes handler path variables based on the active path scheme.
   *
   * @throws Exception
   */
  private function initPathVariables() {
    if (empty($this->pathScheme) || !isset($this->entityInfo['translation']['entity_translation']['path schemes'][$this->pathScheme])) {
      // throw new Exception("Cannot initialize entity translation path variables (invalid path scheme).");
    }
.......

3. Used drush to run db update manually, i.e. drush updatedb, which gave the following output:

The following updates are pending:

entity_translation module : 
  7002 -   Grant 'edit original values' and 'edit shared field' permissions to roles which have entity editing permissions. 
  7003 -   Configure node and comment language settings to the prior default behavior. 
  7004 -   Rebuild entity information to update the path scheme settings. 

Do you wish to run all pending updates? (y/n): y

Performed update: entity_translation_update_7004                                                                                                                      [ok]
Finished performing updates.                                                                                                                                          [ok]

4. Cleared the cache.
5. Edited entity_translation/includes/translation.handler.inc again to uncomment line 1411.

All was good.
