StoreProhibitedCause Exception using the example Storage/List_Files.ino

[Rafdal]

Describe the bug I've tried the example List_Files.ino with the ESP8266 Wemos D1 Mini Lite but during the request it throws an exception (output at the end).

To Reproduce Steps to reproduce the behavior:

1. Open the example List_Files.ino
2. Set all your Wifi and Firebase credentials.
3. Upload and run
4. See error

IDE and its version:

• Platformio Core 5.1.0

Board and framework info PLATFORM: Espressif 8266 (2.6.3) > WeMos D1 mini Lite PACKAGES:

• framework-arduinoespressif8266 3.20704.0 (2.7.4)
• tool-esptool 1.413.0 (4.13)
• tool-esptoolpy 1.30000.201119 (3.0.0)
• toolchain-xtensa 2.40802.200502 (4.8.2)

Additional information

• The Storage is working properly, I've used another Firebase.Storage functions like .getMetadata(...) and .upload(...) without problems.
• Only the Wifi and Firebase credentials are the modified parts of the example, the rest of the code is the same
• I just have 23 files on the Firebase Storage, the names are using 8.3 filename convention (from SD)
• I dont know if this might help but according to a bunch of Serial prints, the exception could be happening at line 596 of FCS.cpp (json.get function)

Your device memory is not enough to handle large JSON payload. The a lot of JSON meta data returned for each file. That's it.

[mobizt]

In case of large server response payload, you need to increase the BesrSSL rx buffer and response size limit as seen in the setup.

If the internal buffer size is not enough to hold the complete JSON payload, the JSON truncated and the subsequent parsing will fail.

Another case is the receive buffer contains garbage due to the reserved memory is not enough for ssl data and payload.
