Subject: Bug Report - Firebase-ESP32 JSON Array Iteration Issue

Dear Firebase-ESP32 Developers,

I hope this message finds you well. I am writing to report a technical issue I encountered while using the Firebase-ESP32 library (v4.3.19) for JSON array iteration.

Issue Description: I have been using the Firebase-ESP32 library to work with JSON objects successfully. However, I noticed an issue when iterating through JSON arrays. Specifically, the problem occurs after the first iteration of a JSON array, where the pointer ofs that points to the value becomes invalid, causing incorrect behavior during subsequent iterations.

Steps to Reproduce:

1. Initialize the Firebase-ESP32 library (v4.3.19).
2. Retrieve a JSON object that contains arrays.
3. Use the iteratorGet() method to iterate through the JSON arrays.
4. Observe that the ofs pointer behaves correctly during the first iteration but becomes invalid in subsequent iterations.

Expected Behavior: I expect the ofs pointer to remain valid and correctly point to the value of JSON array elements during all iterations.

Additional Information:

• Library Version: Firebase-ESP32 v4.3.19
• Arduino IDE Version: 2.1.0 IDE version if relevant]
• Platform: ESP32 Lolin D32 Pro

Impact: This issue affects my project, as I rely on the correct iteration of JSON arrays within my application.

Screenshots: [If applicable, attach any relevant screenshots or code snippets that demonstrate the issue.]

Possible Solution: [If you have any insights or suggestions for a potential solution, please provide them here.]

I believe that addressing this issue would enhance the functionality and reliability of the Firebase-ESP32 library. I am willing to assist in any way I can to help diagnose and resolve this problem. Please let me know if you need further information or assistance.

Thank you for your attention to this matter, and I look forward to your response.

Sincerely, Helmar Alvares helmaralvares@yahoo.com.br

Problem Description: I am encountering an issue with the Firebase-ESP32 library (version 4.3.19) when parsing nested JSON arrays. The library seems to misinterpret the data type of values when nested arrays are encountered, resulting in incorrect parsing.

Context: Here's an example JSON structure and code snippet that reproduces the problem:

JSON: { "keyA": { "node0": "k5g6WzEGh7gdpvnjlySDN63wKKf1", "node1": "-Luic_vkdrxV9PS0AI_D", "array0": { "id_0": [2005, 2006], "w_0": [100, 234] }, "node2": 1693871915, "node3": 1693859573, "node4": 1036 }, "keyB": { "node0": "k5g6WzEGh7gdpvnjlySDN63wKKf1", "node1": "-Luic_vkdrxV9PS0AI_D", "array1": { "id_1": [1033, 1047], "q_1": [3, 2] }, "array0": { "id_0": [2008, 2005], "w_0": [101, 109] }, "node2": 1693873400, "node3": 1693880678, "node4": 1040 } }

Code to Reproduce:

void iteratorJson() { String jsonStr; jsonORDER.toString(jsonStr, false); size_t len = jsonORDER.iteratorBegin(); String key = "", value = ""; int type = 0; for (size_t i = 0; i < len; i++) { jsonORDER.iteratorGet(i, type, key, value); Serial.println("json ---> i: " + String(i) + " key: " + key + " value: " + value); } jsonORDER.iteratorEnd(); }

Expected Result: I expect that when parsing nested JSON arrays (e.g., "id_0": [2005, 2006]), all values within the array should be correctly interpreted as numbers.

Current Result: The current behavior is that, when parsing nested JSON arrays, only the first value is correctly interpreted as a number, while subsequent values are not. For example, "id_0" should be parsed as [2005, 2006], but it is being interpreted as 2005 and 2006 individually.

Library Version: I am using Firebase-ESP32 library version 4.3.19.

Steps to Reproduce: Initialize Firebase-ESP32. Parse the provided JSON structure using the iteratorJson function. Observe that nested JSON arrays are not correctly parsed, leading to incorrect interpretation of values. You can use this description as a basis for reporting the issue to the library's developers. Feel free to adapt and expand upon it as needed to ensure that the problem is well-documented and clear for them to understand.

Message to Developers: I would like to express my gratitude to the developers for their prompt attention to this issue. Your dedication to improving the library is greatly appreciated.

Ok I found the issue but not because parsing but incorrect value copying from source using text find.

The iteration is for elements extraction without parsing.

The problem occurred when the keys contain in the values that cause text search returns invalid index.

I will fix it based on incorrect value extraction.

The new version v4.4.0 with a lot of improvements and bugs fixed is now available.

Please update.
