There seems to be some regression when E2B is used with the newest Next versions. Can you try downgrading Next? In the meantime, we will be looking into fixing properly.

[mwrshah]

Thanks for the suggestion. So far, I've tries downgraded all the way to 14.1 but no-go.

[ValentaTomas]

@mwrshah Can you try upgrading E2B SDK to https://www.npmjs.com/package/e2b/v/0.16.2-beta.44?

[mwrshah]

@ValentaTomas Thanks for the more verbose logging. It helped me to figure out the issue was that somehow system Timezone is being compared to a Z / UTC value. On setting terminal timezone to export TZ=UTC this was resolved.

[mwrshah]

I take that back - this is still a problem. Consistently facing an issue with creates and connects both with the beta version - works reliably with CLI. Could it be that I am doing

const sbx = await Sandbox.connect(sandboxId) await sbx.setTimeout(600_000)

Instead of await Sandbox.setTimeout(sbx.sandboxId, 600_000)

Having more success with the second.

[mwrshah]

Now fixed. Might have been an infrastructure issue as discussed with the team.
