Manage Dates error: Object reference not set to an instance of an object

[hermann-pbi]

Describe the problem

Every time I connect to the ‘Manage dates’ section to update my ‘Dates’ table I always get the same error, whereas everything works normally for the other sections. Can you please check this? Thanks in advance

Hi @hermann-pbi, We’ve checked our telemetry and can see the error, but to investigate further, we’d need a bit more information. Would it be possible for you to share a PBIX file with dummy data (no sensitive information) and just the minimal tables needed to reproduce the issue ? This would really help us identify the root cause. Thanks

We’ve investigated the issue further but were still unable to reproduce the error on our side. However, we’ve implemented a change and released a development version for testing to determine if it addresses the issue. It would be very helpful if you could test it on your end to confirm whether the issue is resolved or if it still persists.

To get the latest development build, you can switch your update channel from Stable to Dev in the Options > About panel and follow the link to download the installer. Alternatively, you can download the version directly from https://bravorelease.blob.core.windows.net/bravo-internal/2024/12/05/20241205.3-1.0.9105.27868/Bravo.1.0.9.x64-portable.zip ( https://bravo.bi/builds )

If the problem persists, it would be very useful if you could provide additional details to help us reproduce the error and, if possible, also sharing a PBIX file with dummy data that replicates the issue.
