ContactsStorageException because of apostrophe in address book name

[joshuakraemer]

I can't sync my vivaldi.net address book to my mobile phone, because the backend crashes due to an apostrophe in Davx5's auto-generated address book account name.

Details: When I add my vivaldi.net account to Davx5, it always creates an account with both a CalDav and CardDav service because of the service discovery on the server. My vivaldi.net address book is called "joshua's addressbook". Thus, Davx5 creates a calendar account using my mail address as the account name and a separate addressbook account with an auto-generated name like "joshua's addressbook (mail address) #1". When trying to sync this account, the backend crashes with a ContactsStorageException, presumably due to the apostrophe in the account name. I thus have the following questions:

• Is it possible to disable service discovery, so I can create separate Davx5 accounts with custom account names for vivaldi.net's calendar and address book?
• Is it possible to use both calendar and address book with a single Davx5 account (without the auto-generated separate address book account)? I don't want to sync multiple address books.
• Is it possible to rename the address book account (removing the apostrophe)?

Which device / Android firmware / version do you have? Apostrophes shouldn't be a problem, but some devices have problems. (This is why the DAVx5 account setup recommends not to use apostrophes in account names. But in your case, it's not the DAVx5 account name that makes problems, but the address book account name, which you can't influence if I understand it correctly.)

When trying to sync this account, the backend crashes with a ContactsStorageException, presumably due to the apostrophe in the account name.

Can you please share the debug info to https://www.davx5.com/support, mentioning this issue? So that we know which devices have problems and which problems.

No.

Is it possible to use both calendar and address book with a single Davx5 account (without the auto-generated separate address book account)? I don't want to sync multiple address books.

No. Android doesn't know the concept "address books" (only contacts), so we have to map CardDAV address books to address book accounts.

Is it possible to rename the address book account (removing the apostrophe)?

Unfortunately, not manually.

Can you rename it on vivaldi.net?

However DAVx5 shouldn't use special characters (and especially apostrophes) in auto-generated account names. We will track this in an issue.

My phone is a Realme 5 Pro (RMX1971), running Android 11 (Realme UI 2.0).

Can you please share the debug info to https://www.davx5.com/support, mentioning this issue? So that we know which devices have problems and which problems.

I'm sorry, but I don't feel confident to share the debug info generated by Davx5, because it contains personal informations about my contacts (e.g. phone number) and maybe other sensitive data.

Can you rename it on vivaldi.net?

No, the address book is created by Vivaldi.net automatically.

Thank you very much for your help and effort. I hope this issue will be resolved, so I can start using Davx5 on my phone. Still, I think it would be useful to have more manual control in the app, e.g. disabling service discovery to only connect with required services or custom names for the generated storage accounts.
