Unable to retrieve CloudWatch Logs Insights queries filtered by query language "CWLI"

[cosborne83]

Describe the bug

The logs describe-queries command supports a --query-language option that should allow filtering at the API level for queries in a specific query language (CWLI, SQL or PPL). This appears to work for the "SQL" query language, but not for "CWLI".

A client-side filter using --query shows that I have logs insights queries with both "CWLI" and "SQL" query languages:

> aws logs describe-queries --query "length(queries[?queryLanguage=='CWLI'])"
52

> aws logs describe-queries --query "length(queries[?queryLanguage=='SQL'])"
20

Performing the same filtering via the API filter using the --query-language option produces the same result for "SQL" query language, but no results for the "CWLI" query language:

> aws logs describe-queries --query-language CWLI --query "length(queries)"
0

> aws logs describe-queries --query-language SQL --query "length(queries)"
20

Am I doing something wrong, or is this a bug in the CLI and/or API?

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Using the --query-language CWLI option to aws logs describe-queries should return the queries with query language "CWLI".

Current Behavior

No results are returned.

Reproduction Steps

1. Perform a CloudWatch Logs Insights query using query language CWLI via the API/CLI/console.
2. Run aws logs describe-queries (without the --query-language option) to confirm the query from step 1 is included in the results and that the queryLanguage is CWLI.
3. Run aws logs describe-queries --query-language CWLI and check whether the query from step 1 is included in the results.
