Attribution of previously unattributed phrase failed

[matchachoco95]

Describe the bug
When trying to attribute the previously unattributed binom 武人, I got an error message. I tried reloading the page and even closing and reopening my browser, but the issue persists. I had no problems creating new attributions for words that had already been attributed.

To Reproduce
Steps to reproduce the behavior:

1. Go to the text (國語 in this case; https://hxwd.org/textview.html?location=KR2e0001_tls_004-216a.51&query=%E4%BB%81%E4%BA%BA%E4%B8%8D%E9%BB%A8#)
2. Mark 武人 and try to add an existing concept to it.
3. See error message shown in screenshot below.
