Hi, I used Vikunja (docker vesion self hosted) from some weeks now. Some " problem " seems to be corrected in unstable version. I try to only change the tag of the docker’s image but I lost some informations in the front-end (like project affected to tasks or priority) and I have an error " valid character ‘d’ looking for beginning of value " when I try to make a project from filter). I didn’t find any answer in documentation and in this forum. Maybe I didn’t search properly. I’d love to continue testing this tool, which seems very promising. 🙂 Regards. DerO ---

Welcome 👋 Did you switch to the `unstable` tag? Which version do you see in the about dialogue in the frontend? ---

Thank you for you message. Yes, I switch ti the unstable tag. This is what I have in the about dialogue : > Frontend version: dev > API version: v0.24.1-1430-648f6f6a ---

All my tasks seems to be there but without any project. ---

So no projects in the menu on the left? Do you see any projects when running `select * from projects` in your database? ---

When I try to refresh projects page in the frontend, here is the log : > 2025-06-23T12:32:54.847057874Z: INFO ▶ [DATABASE] 200 [SQL] SELECT “id”, “title”, “project\_id”, “view\_kind”, “filter”, “position”, “bucket\_configuration\_mode”, “bucket\_configuration”, “default\_bucket\_id”, “done\_bucket\_id”, “updated”, “created” FROM “public”.“project\_views” WHERE “project\_id” IN ($1,$2,$3,$4,$5,$6) ORDER BY position asc [1 2 3 4 5 -2] - 1.955714ms > 2025-06-23T12:32:54Z: ERROR ▶ 201 invalid character ‘d’ looking for beginning of value ---

OK, I try something : export data from 0.24.6 with the export task in the frontend an import it in a new unstable instance : doesn’t work. Look the error and seems to be in the filter filed views. Expected something like : > “filter”: { > “s”: “”, > “sort\_by”: null, > “order\_by”: null, > “filter”: “done = false”, > “filter\_include\_nulls”: false > }, and data in my file, for example : > “filter”: “done = false \u0026\u0026 (due\_date \u003e= now/d+1d \u0026\u0026 due\_date \u003c now/d+2d)”, I put all my view filter to > “filter”: null, And the import is OK (without filter of course). ---

I’m unable to verify this with the latest unstable build (`v0.24.1-1442-247d82f0`). Do you only see this when fetching projects? ---

It seems like it’s only on projects. I solve my problem (but not THE problem) by exporting from 0.24.6, change the filter field (only 24) and import in a unstable fresh install. ---

Same here, first I thought it could be something with OIDC and shared projects but none of any projects have been imported in the latest unstable. I also updated from 0.24.6 by just changing the docker tag. After that I panicked because my latest update was 23h ago and 80 people have made their changes on their projects during the day so i just changed vikunja back from unstable to v0.24.6. Sadly I now face various issues like no filter views (like @Jerome_Desroziers described) list view in generell: error.4024 The filter expression '{“filter”:“done = ‘false’”}" is invalid: unexpected character ‘{’, no new oidc group synchronisation even after logout/login. This evening I plan to repair at least the 0.24.6 instance like this: - Export current broken 0.24.6 data with Vikunja \> Settings \> export vikunja data - restore backup from 2 days ago - import newest data from broken vikunja - cross fingers Is this maybe going to work @kolaente? I will test this first in a test environment, should have done it also before the upgrade yesterday. The reason why I updated in first place is because an employee asked me if she can sort a kanban bucket with newest items on top instead at the bottom. With [try.vikunja.io](http://try.vikunja.io) I discovered that the newest unstable version is doing it like that. perfect i thought and just changed the docker image tag _facepalm_ edit: Frontend-Version: dev API-Version: v0.24.1-1541-6deb0699 logs after trying to import the data from 0.24.6 to latest unstable: Error 308 could not read data: json: cannot unmarshal string into Go struct field ProjectView.Project.views.filter of type models.TaskCollection after replacing “filter”:“{"filter":"done = false"}” with “filter”:null the following error occurs: could not read data: invalid character ‘\’ after top-level value after replacing all '\'s: could not read data: invalid character ‘U’ in string escape code @kolaente should I confidentally send you my export.zip so you can debug it? I dont know if thats the right way I am doing it right now, and you might be interested in that for future updates from 0.24.6 edit 2: apaerantly there seems to be an issue with URLs in the title or description of a task. The following extract could be creating a syntax error: …`{"id":630,"title":"FBS - Telefone im und 3. OG","description":"\u003cimg src=\"https://ca.slack-edge.com/T02-123XYZ-48\" alt=\"\"\u003e\u003cp\u003e\u003cstrong\u003eMAXI MUSTERMANNMAXI MUSTERMANN\u003c/strong\u003e\u0026nbsp;\u0026nbsp;\u003ca target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"c-link c-timestamp\" href=\"https://MEINWORKSPACENAME.slack.com/archives/C08C20/p1719\"\u003e13:44 Uhr\u003c/a\u003e\u003cbr\u003e\u003c/p\u003e\u003cp\u003eDas Telefon im 2.

Welcome! 👋 > [@Simsala](#): > > logs after trying to import the data from 0.24.6 to latest unstable: This is not supported. You can only import dumps between the same versions of Vikunja. The way to upgrade from stable to unstable (or to a newer release, for that matter) would be to update the docker image / binary and then restart Vikunja. This will run all migrations automatically. Dumping from a stable version and importing into a newer version won’t work. Same for migrating back from newer versions to older. What made you roll back from unstable in the first place? > [@Simsala](#): > > no new oidc group synchronisation even after logout/login. Did you adjust the config?
