Tasklist form appears blank

[30carterjack]

Hi,

I’m running Camunda 8 with all components as Docker Containers. I’ve recently started experiencing an issue where a specific form in one of my processes will appear as a task within Tasklist. However, when you select the form no content actually appears and the entire form is blank. The underlying form has required fields, meaning that this process is unable to continue.

Any experience with this before?

Thanks,

Jack

This sounds like a common issue with Camunda 8 Docker deployments where forms appear blank due to various configuration or data export problems. I found the following relevant resources:

• User Task Not Visible in Task List - covers Tasklist V2 mode issues in 8.8+
• Migrate to Camunda user tasks troubleshooting - embedded vs linked forms issues
• Process deployed, but not listed on operate ui - Zeebe export pipeline problems
• Task Forms not showing data after update - post-upgrade form data loss
• Tasklist UI mode configuration - switching between V1/V2 modes
• Form linking - Camunda Form (linked) - known bugs in 8.4.0-8.4.2

Does this help? If not, can anyone from the community jump in?

Unfortunately these links do not help. There have not been any updates/migrations recently.

Hi @30carterjack
Have you checked the browser console and server logs for any errors when working with that specific form?

Hi Alex,

Appreciate the comment. Yes I’ve checked across container logs and haven’t had much luck so far. Unfortunately we receive quite a lot of errors and warnings as normal so hard to identity those that ‘matter’. Do you know which specific service container would be relevant here? (e.g., tasklist, zeebee, etc)

I think Tasklist would be more relevant in this case.
Did you make any changes or redeployments to this process? Did the issues start happening all of a sudden?

I’ll take another look. No changes or deployments made recently. Issues started happening all of a sudden. The only event that took place nearby was removal of dated indices from elastic - but this is relatively routine and hasn’t caused issues before.

Do you have the possibility to redeploy this process with some cosmetic changes and check if it makes any difference?

Also, you can try the Tasklist REST API to check the form(Get a form | Camunda 8 Docs):

curl -s http://<tasklist_host>:8080/api/forms/

Does it return anything?
