getting unknown system error in node fs on EFS mounted directory

[aman-gupta-doc]

Hi everyone,
I got below errors multiple times when using node fs write or read functions.

Error: Unknown system error -116: Unknown system error -116

Why I am getting those errors?

Linux, right? EFS is a network file system and 116 is EISCONN, so presumably the connection with the backend got in some kind of bad state.

I doubt node is the culprit here, it's probably just the messenger. That error code comes straight from the kernel. Check the kernel logs.

Thank you, @bnoordhuis, for your answer.

Yes, My OS is Linux. As I can check in Linux error code list, error number 116 pointed to ESTALE and for EISCONN they have error number 106.
Can you help me with understanding why I got ESTALE on writing file?
