Configuration page for newly installed SparkPost extension error: Cannot decrypt token. Invalid format

Question

Sorry, due to an error, we are unable to fulfill your request at the moment. You may want to contact your administrator or service provider with more details about what action you were performing when this occurred. Cannot decrypt token. Invalid format. Return to home page.

I have installed the SparkPost extension for CiviCRM 5.39.0 on Drupal 7.82. I have ensured that the installation steps 1, 2 and 3 here are complete. When attempting to follow step four, going to Administer > System Settings > Outgoing mail (SparkPost) I receive the above error on the screen.

I have cleared caches and double-checked paths.

Google search shows exactly one post with this verbiage but I am not able to figure out the relationship between that one issue and this: https://lab.civicrm.org/dev/core/-/issues/2563. It only comes up here as part of the exceptions thrown verbiage in the codebase.

Note: I am working on getting CiviCRM updated, but since CiviSMTP is kaput by Aug 1, 2022, I was hoping that updating CiviCRM was not the solution.

Please let me know what else I can try, thank you!

Answer 1

Install from git. The sparkpost-1.5.tar.gz was released after fixes for this were committed in July, but for some reason aren't in the release.

Answer 2

It might also be that your crypto keys in civicrm.settings.php aren't using a valid format. The docs are a bit difficult to follow to figure out how to generate a proper key. You can use this tool: https://civisettings.symbiotic.coop

Note you need to REPLACE the existing lines for CRED_KEYS and SIGN_KEYS in civicrm.settings.php with the output, not add more lines to the file at the end, since then the existing lines will still get used.

You may also need to clear out any existing api key and re-enter it on the admin page to get it re-encrypted. You can delete it in mysql directly with delete from civicrm_setting where name='sparkpost_apiKey';

Also make sure you are using the latest version of sparkpost - note there were some changes added last week related to crypto.

Answer 3

Seems the fix for this is in git, but is not in the zip even though v1.5 was tagged after fixes were applied for some reason isn't in the sparkpost-1.5.tar.gz

Suggest "git clone [email protected]:extensions/sparkpost.git". Then delete the .git folder in the sparkpost extension directory as you probably don't want to keep that.
