Anki is connected, but anki cannot generate a new card

[lily8186]

obsidian v1.6.7,Obsidian_to_Anki v3.6.0，
After clicking the generate button, only these two prompts appeared and no new card was generated in Anki. May I ask where I did wrong?


The used regular expression :
((?:[^\n][\n]?)+) #flashcard ?\n*((?:\n(?:^.{1,3}$|^.{4}(?<!<!--).*))+)
Used test file :
START
Basic
This is a test.
Back: Test successful!
END

In Neuracache style, to make a flashcard you do #flashcard
The next lines then become the back of the flashcard
