I am trying to upload files from the kotlin react app to the backend. It works fine for little sized files but as soon as I try to upload a file bigger than ~1MB I get the following error:

IllegalArgumentException: should should be greater than write space + end gap (size = 9, writeRemaining = 0, endGap = 8, rem+gap = 8

The network request functions are written in the multiplatform commainMain sourceset so that they can be shared with Android and iOS in the future. I tried using .post, .submitForm and .submitFormWithBinaryData without seeing any success.

Here's a repo with the 3 projects side by side for you to reproduce the issue: https://github.com/galex/reproducer-bug-ktor

Thank you,

That's quite interesting state when size = 9 here. I'll investigate it asap.

Is there a nightly build or something to test the fix?

Fixed in 1.1.3.
