Integration Issue with Nodemcu ESP8266, ADXL345, and Micro SD Card Module

Using Arduino Storage
1

Hello,

I am attempting to create a system using Nodemcu ESP8266, ADXL345, and a Micro SD card module. My goal is to read acceleration values (x, y, and z) from ADXL345 and write them to an SD card. Both the SD card and ADXL345 modules work flawlessly individually. However, when I combine these modules, I encounter the following error. How can I resolve this issue?
