Can't create topic with tags

[Rick_Jing]

I tried to create topic with tags, got 500 internal server error,
there’s no permission issue, I can create topic without tags via API and create topic with those tags on the web application.
is anything I missed here?
edit: re-upload the screenshot

Your api key and username are still readable, please invalidate that key ASAP.

how could people see it?

Because it is not entirely black.
With a little editing you can easily read it

thank you, didn’t check carefully, I disabled the api key.

NoMethodError showed in the log.
solve it by using "tags[]": ["test1","test2"]
thanks everyone who replied.
