## Tags

* type: bug

* keywords: gn2, genenetwork2, genenetwork 2, collections

## Description

### Steps to Reproduce
* Go to https://genenetwork.org/
* Ensure you are logged out
* Now, navigate to https://genenetwork.org/show_trait?trait_id=1435464_at&dataset=HC_M2_0606_P
* Click green "Add" button
* Note silent failure, then "MissingTokenError: missing_token: Please log in again to continue." notification

### Expected

On clicking "Add" we should have got a modal dialog with a selection of collections we can add the trait to.

### Notes

#### Cause of Failure

=> https://github.com/genenetwork/genenetwork2/blob/c057054b69e673108410894ce87c5059aebb7b68/gn2/wqflask/collect.py#L81-L84
The first fetch with ``oauth2_get`` fails in the case where the user is not logged in, raising a "MissingToken" exception. This then is handled by the default handlers and we get presented the prompt to login.
