📝 WalkthroughWalkthroughThe initialization script validates existing agent configuration files, accepts plain JSON or base64 input, validates generated content, and atomically replaces the target file. ChangesAgent configuration validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The initialization script can currently accept partially decoded configuration or reject valid plain JSON when jq is unavailable, potentially leaving the agent with invalid configuration or preventing startup. These bounded correctness issues should be fixed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@src/deploy/NVA_build/noobaa_init.sh`:
- Around line 130-139: The AGENT_CONFIG decoding flow must reject decoder
failures before installing the file: capture and validate the exit status of
both base64 and openssl decoding commands, then retain is_valid_json_file
validation for silent or partial output. Ensure jq is available in the NVA image
by adding it to the image dependency list, or fail clearly when it is
unavailable so plain JSON is not incorrectly sent through base64 decoding.
- Around line 123-125: Update the AGENT_CONFIG handling around the jq
availability check so plain JSON is always written directly with printf before
validation. Use is_valid_json_file to validate the resulting temporary file, and
only fall back to base64 decoding when the direct value is not valid JSON;
preserve support for environments without jq.

Do not require jq to accept plain JSON.
When jq is unavailable, valid AGENT_CONFIG is sent to base64 -d and initialization fails validation. Write the value with printf, then validate it with is_valid_json_file.

Reject failed base64 decodes before JSON validation.
base64 -d can return non-zero after writing a valid JSON prefix. Since the script ignores the decoder status, malformed AGENT_CONFIG can pass JSON validation and be installed. Check the status of both decoders, then retain JSON validation for silent or partial output.
- Install
jqin the NVA image or fail clearly. The image dependency list does not includejq, so valid plain JSON is sent to the base64 path whenjqis unavailable.

@naveenpaul1 did you test this code on a downstream image? I think that we don't have jq installed on the DS image and this might even be the root cause for the bug.
did you consider decoding the base64 json in the operator side? This should eliminate this entire code
