Failing to ask the bot to credit a user for research work

[Lucas-C]

Describe the bug
The @all-contributors bot fails to add the research contribution to an existing user (already in .all-contributorsrc)

To Reproduce
I simply used the following syntax:

@all-contributors please add @moe-25 for research

Expected behavior
I expected the bot to create a commit on the repo that would add the new contribution to the user

Same behavior here.
