JavaScript Error in Time Series Studio

Bay — Tue, 27 May 2025 09:18:07 GMT

Hi, I am using the LPC55S69 EVK board and test on time series studio (latest version), but sometimes (data logging, emulation) it will prompt this error.

Please assist.

Hi @Bay

“ (data logging, emulation) it will prompt this error.”

May I ask if this error frequently occurs?

We want to reproduce this issue.

But according to the error message.

Uncaught Exception:
Error: EPIPE: broken pipe, write

This typically indicates that the main Node.js process tried to write to a stream (like a file, socket, or pipe) that was already closed or unexpectedly disconnected.

Hi Harry,

Yes, it occurs frequently. Now I am training the data, and it keeps prompting this error.

And also, when programming the time series studio firmware, it also keeps prompting this error. But at the end, it programs successfully.

Hi @Bay

Did you turn off eIQ Portal when using Time Series Studio？

Please do not turn off eIQ Portal when using Time Series Studio.

Hi Harry,

I closed the eIQ Portal when using Time Series Studio.

I've reopened it, and the error hasn't been prompted so far.

Thanks for the quick response!
