How to effectively update APISIX route rules

I am completely new to APISIX and I am following the getting-started tutorial.

The problem is in editing routes. More specifically, I create a route using this example of the tutorial and it works as expected. Next I am editing the route's uri using:

# Please notice the extra 'g' in the uri value 'anythingg' compared to the previous uri
curl "http://127.0.0.1:9080/apisix/admin/routes/1" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" -X PATCH -d '
{
  "uri": "/anythingg/*"
}'

Then I am trying to connect to the endpoint using the new and the old uri but I am getting an 404 in both cases with different messages! The requests-responses: New uri

$ curl -i -X GET "http://127.0.0.1:9080/anythingg/foo?arg=10" -H "Host: example.com"
HTTP/1.1 404 NOT FOUND
Content-Type: text/html; charset=utf-8
Content-Length: 233
Connection: keep-alive
Date: Tue, 13 Sep 2022 09:13:40 GMT
Access-Control-Allow-Origin: *
Access-Control-Allow-Credentials: true
Server: APISIX/2.15.0

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>404 Not Found</title>
<h1>Not Found</h1>
<p>The requested URL was not found on the server.  If you entered the URL manually please check your spelling and try again.</p>

Old uri

$ curl -i -X GET "http://127.0.0.1:9080/anything/foo?arg=10" -H "Host: example.com"
HTTP/1.1 404 Not Found
Date: Tue, 13 Sep 2022 09:13:45 GMT
Content-Type: text/plain; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive
Server: APISIX/2.15.0

{"error_msg":"404 Route Not Found"}

How could I update the route rules and get the expected results and what is the cause of the observed behavior?

Thanks!

Solution

The error in the new URI indicates that it was returned by httpbin, not APISIX; in the old URI, it was returned by APISIX.

You can update the route in its entirety via the PUT method to ensure it is updated successfully.
