Cannot export custom fields in trello

Hi, I'm currently planning to use trello Andrés custom fields Power ups but It seems that info is not properly saved/exportes on Json once you change any value on the custom fields.

Is this correct? Is any action required un order to save changes?

Thanks in advance.

The custom fields are exported in the JSON and CSV. In the JSON, you'll find a `customFields` property at the root object for the <board>.json. Those describe the custom field definition/schema.

In the `root>card` property, you'll find the `customFieldItems` property for each card that has a custom field on it.

Are you not seeing these in your export?

FYI -- we've identified the bug and are working on a fix. Sorry for the inconvenience.

@Rich Manalang - is there anywhere we can follow updates on the bugfix so we know when this is resolved?

Hi Alex. This issue is now fixed. The fix deployed this morning. Sorry for the inconvenience.

Thanks, Rich!

Great.Thanks !

@Rich Manalang - since this was resolved, I've noticed what appears to be another bug. While using a CSV export, I discovered that there was a lot of custom field data missing, and it turns out the values for one of my custom fields was de-selected in quite a few cases. I have a lot of historical cards in this board and the data is missing from quite a few cards, even though the value still exists in the dropdown selection.

I can't find a correlation between the missing values and the missing values appear to have happened on random cards. I will now have to go through hundreds of cards and re-apply the missing value one by one.

A couple questions on this:

  1. Is this a known bug as a result of the updates to how custom fields work?
  2. Are there any other additional changes coming to the custom fields power-up functionality in the near future?
  3. Somewhat related - what are the maximum number of custom fields allowed, and how many values can I input into a dropdown? This seems to have changed, but I can't find this documented anywhere.
