524 Error Encountered

Encountering several different error messages when uploading a csv file. 524 error message was the last and reading through the error mentions something about CloudFlare.

It sounds like the importing files seems to be too large (number of the rows as well as expressions for appformula/initial values as we discussed in the other post.

Yes Koichi-san,

That could definitely explain it. I have updated the Troubleshooting CSV Import article to cover timeout better. See topic “Timeout Occurred or Import is Taking Too Long” in this article Troubleshooting CSV Import | AppSheet Help Center

Thanks for taking out time to respond.

I have cleared out and started loading again. I still encounter the error but the data seems to be uploading successfully.

Will document further and log a bug report if issue does not go away.
