Bulk tag creation rejects tags with uppercase letters

When creating tags via bulk tag creation, tags that contain uppercase letters (for example “UppercaseTag”) are rejected with an “Invalid tag name” error.

This is surprising from a user perspective, because the same tag names work when entered for example through the regular topic UI

Depending on the force_lowercase_tags setting:

Bulk tag creation behaves differently:

  • it rejects tags containing uppercase characters even when they are allowed by the force_lowercase_tags setting
  • instead of accepting the input and applying the usual normalization, it fails validation outright.

As a result, users have to manually adjust their input (for example by converting everything to lowercase), even though this is not required anywhere else. Since the same input works in other parts of the UI, it is difficult to understand why tag creation fails specifically in the bulk workflow.

Would it be possible for bulk tag creation to use the same validation and normalization behavior as the other tag input paths, so users don’t have to learn a separate set of rules for bulk operations and to ensure that creating tags with uppercase letters is possible in bulk?

Thanks for the report.

We’re currently making some sizeable changes to tags, so we’ll have a look at this after.

Thank you!

This seems to work now. I was able to create UppercaseTag when Force lowercase tags was disabled.

And when I disabled the setting, I was still able to create UppercaseTag, and it was converted to lowercase

Is there a reason why the other magic fixes that happen when I create a tag in the composer are not applied when I use bulk create?
For example, I cannot create a tag with 2 dashes in bulk create

But it works in the composer
