Issue Description
I am using ESP32 Wroom 4MB and I am trying to upload a file to Firebase Storage from SD card. I am getting fcs callback error as "response payload read timed out due to network issue or too large data size" which looks similar to the issue #315 in Github Library https://github.com/mobizt/Firebase-ESP- ... ssions/315. I have two Firebase libraries ([Firebase-ESP-Client]https://github.com/mobizt/Firebase-ESP-Client & Firebase-ESP32 https://github.com/mobizt/Firebase-ESP32 which was installed using Arduino's Library Manager.

I am using hspi pins for reading and writing the files from my SD card. I am sharing the example code to upload a file to Firebase Storage with slightly modified code for my hspi pins which used to work earlier but after that I updated the arduino core and Firebase libraries but since then it stopped working. I was using SPI call function to access the SD files which used to work. In the sample code below I have commented the hspi part to use SdFat library https://github.com/greiman/SdFat but that also gives me same error. I am not sure if I have configured my FirebaseFS.h and SDHelper.h library. I have attached my FirebaseFS.h and SDHelper.txt library for your reference let me know if I need to modify anything else. I haven't modified anything in SdFat library.

I have tried using ESP core 2.0.1,2.0.3 & latest 2.0.4 versions. For Firebase library I have tried using 4.0.0 for both libraries. I have also tried Firebase ESP client with v3.3.3. Since I am using Firebase32 example for cloud storage upload I am not sure what version of Firebase32 library I should use as you have shared v3.3.3 of Firebase ESP Client to be working. Since there are two libraries it gets little bit more confusing and complicated for me as it might be causing conflicting issues due to different versions and I don't know what files are used during compilation of the code.


Questions

1. What version of library I should use for Firebase32, Firebase ESP Client, SdFat as well as ESP Core.
2. To be on safe side I update FirebaseFS and SdHelper files in both library location. Do I need to update anything else? Does my file configuration look good to use SdFat with hspi pins
3. What should I comment out in library and in my code below if I want to use HSPI calls from my code. Currently HSPI part of code is commented below
4. I have disabled OTA to get extra memory on my ESP32 and currently having 2MB for APP and 2MB for SPIFFS. Could this cause an issue?


IDE and its version:

Firebase ESP client
- Version [3.3.3, 4.0.0]// I don't remember which version I was using earlier when my code used to work with hspi calls

Firebase32
- Version [4.0.0] // I don't remember which version I was using earlier when my code used to work with hspi calls

SdFat

You can use any version of the Firebase library but it requires a specific version of the Json library. For me, it works with ArduinoJson library 5.13.3 for me. I followed this tutorial https://microcontrollerslab.com/google- ... duino-ide/and it worked.
