"location" key in worldgen/templatepool has incorrect report

[AiJYGR]

As the title suggests

At the bottom you can see it shows "Can't find the structure"
But at the left you can see the files and the folders are all correct.
Also, in the game, the datapack runs well, and the structures also generate as expected.

In fact, nothing went wrong when I just started editing this part.
But less than 30 minutes I could say, It went wrong.
Is that a Data Overflow bug or something like this I guess? :(

Never mind the line 17 QwQ
