Custom Card with HTML File Shows Server Error in Client App and Causes Sync Failure

[dinesh2096]

When a Custom Card is configured with an HTML file in the Web App, the corresponding card fails to load in the Client App. Instead of displaying the configured content, the Client App shows a Server Error. Additionally, the sync process fails when this Custom Card configuration is present.

Env : Pre-release
org : gubbachi
user : maha@glc
db: realm
version 1-2ab81
Release: 17.2

Steps to reproduce:

1.Login to the cilent app
2.Attendance dashboard
3.Click on the card which as html files

Actual result : The Custom Card displays a Server Error in the Client App. The sync process also fails when the Custom Card with the HTML file is configured.
Expected Result : The Custom Card should load and display the HTML content correctly in the Client App.

@dinesh2096 does this work as expected in 17.X?

[dinesh2096]

@himeshr forgot to mention it happens in 17.2 also

• Marking this 17.3, we would need to check with support to see if this issue exists on prod version app and impl config.. the card issue might be impl team fix.. Evaluate that first, if changing to simple html solves the issue, then only investigate and fix the sync issue cause
• If rendering still breaks, then we do fix for both html rendering and sync issue

@dinesh2096 Could you check the above can be done by yourself, might be cheaper to close out this analysis for you

@himeshr, test with the HTML file, and the query works in 18.0, 17.3, and 17.2 in the pre-release, but I don't know why the oldest one is getting an error

Org test: dineshbootcamp
User: dummy@dineshbootcamp
card name: HTML file
