*WARN* PersistedQueryServlet Cannot recognize GraphQL query type:

[SCBM]

We are getting below WARN logs, Although it looks like the query executes successfully and returns data
GarphiQL window works fine too with returning the proper response.

On checking the jar code for PersistedQueryServlet.java, it seems this WARN message is displayed may be because of the Query Syntax, since the code looks for pattern "List{items{"  to check if a Query is of a List. [ Please refer below image], whereas  my GraphiQL query has the pattern:
"generalMessageList(filter: {code: {_expressions: [{value: $code}]}},_locale:$locale) {
__typename
items {
__typename....
"

i.e "List(filter" 

Can you please share what , if any, corrections should be made for the Query syntax ?

boolean isQueryList(String query) {
    return StringUtils.deleteWhitespace(query).contains("List{items{");
  }

@SCBM 

By looking at code snippet you attached as image, it looks like it will log the warn message every-time because it's outside if statement.

Can you please re-check the Java servlet code once?

[SCBM]

Hello @iamnjain 

The two "if" statements have a single "return" statements. So in case any one of the if condition is  true, it will return without executing the logger  "warn"  message.

I would recommend logging this as a bug as your query syntax looks perfectly valid.

I can't reproduce the error with similar queries.  Are you on cloud service on the latest release?

[SCBM]

Hello @martin_ecx_io 

Yes, we are on cloud service. Can you please share which latest release version are you referring to? Will cross check it with what we have in our case

[martin_ecx_io]

The cloud service instance i tested on is running version 2025.1.19352.20250131T194709Z
you can check the version in Cloud Manager for each environment

On my sandbox env it shows the following as the latest version available currently:

Did you end up raising an Adobe ticket for this? Any resolutions?
