Hey @nirkons,

We have created an internal ticket to look into this which we will be tracking as "N8N-7970"

Hey @nirkons

Do any errors appear in either the browser console or in the n8n logs?

Hey @nirkons

Do any errors appear in either the browser console or in the n8n logs?

In the docker logs I didn't see anything, do I need to set any parameter in the docker compose to see debug logs?

The console I didn't check, I'll check and update Thanks

Hey @nirkons

Do any errors appear in either the browser console or in the n8n logs?

index-fCEqBD8K.js:14301 GET https://example.com/rest/executions/837404 net::ERR_CACHE_WRITE_FAILURE 304 (Not Modified)

this is the only thing in the console, nothing in the docker logs, but im unsure if i need to increase debugging in docker?

thanks

Hi @nirkons,

Could you please clear the browser's cache data? If the problem persist it would help us to reproduce it ourselves if you could provide us a sample file to test it.

Thanks

Hey @nirkons!

We haven’t heard back for a while so we’re going to close this for now.

If you’re still running into the issue, or have more details to share, feel free to reopen it or create a new one.

Thanks!

Hey, I can confirm this exact error on my instance too, happy to work with you with any info you need.

[nirkons]

I'm still having this issue, I could not get any logs, nothing shows up even when increasing logging level.

The only thing is that the run itself is about 250MB in the DB when getting it from sql.

Maybe you can reproduce by creating a similar scenario

Download a docx file from google drive, convert it to html with mammoth, add another function node and make changes to this html (doesn't matter what), add another function node and convert back to docx with html-to-docx, upload to Google drive
