txn_box plugin error in example

[anonymous-bugs]

Does this txn_box example work?

txn_box:

• when: upstream-rsp
  do:
  • with: [ upstream-rsp-status , proxy-req-path ]
    select:
    • as-tuple:
      • eq: 404
      • match: "example"
        do:
      • debug: "Resetting upstream response"
      • upstream-rsp-status: [ 200 , "OK" ]
      • upstream-rsp-field: "max-age=3600"

Error:
While parsing as-tuple comparison at Line 5.
While loading "with" directive at Line 3 in "select" at Line 5.
While parsing directive at Line 3.
While loading directives at Line 3.

When i also use

• with: upstream-rsp-status
  select:
  • eq: 200

It gives error.

@cmcfarlen @brbzull0 can you look into this?. Im using trafficserver 10.2.0

I'm not really familiar with txn_box syntax, but think in header_rewrite that would be like

cond %{READ_RESPONSE_HDR_HOOK} [AND]
    cond %{STATUS} =404
    set-header @newstatus "Resetting upstream response"
    set-status 200

@mlibbey Thanks for your response. I'm looking to build more complex examples, so was testing provided examples since my logic kept running into error. I dont know if etags can be compared during header_rewrite

I added a test that exercises the example txn_box code. It seems to work in the test. See #13581 . I'm going to close this issue. Please feel free to re-open if I'm missing something and there is something else to investigate.
