📋 Summary

Related Issue: Fixes #8745

Increase signed URL expiration time to 3600 seconds to allow large file uploads.

🎯 What

🤔 Why

Large files fail to upload before the 10 minute signed URL expires, even with a decent connection.

🔧 How

Increases timeout to 3600 seconds.

Is there anybody who could take a look at this 🙏 ? I'm totally blocked by this! The final step before my product goes live is testing the checkout flow with Polar but I can't upload my files!

Maybe @Yopi @psincraian @frankie567 (apologies if I'm tagging the wrong people or missing anything from the PR, but it is a simple one).

Hi @obrienciaran, thank you for the PR, and solving the issue on your own! I think we might want to rework this or have a different way to upload large files to avoid hitting this timeout when the user has a slow internet connection, but I think for now this works -- if it's enough for you.

[obrienciaran]

Thank you very much @Yopi

It's an interesting one - I tried to upload on a few different networks, but each timed out on a 2.9gb upload with the short window. I think the solution of simply increasing the signed URL is sufficient for now. But I look forward to new developments in future 😄 Thanks for jumping on this so fast.

[Yopi]

No worries. The change should be out in production now @obrienciaran. I hope it's smooth sailing from now on, but otherwise let me know!

I just had another look @Yopi , I see that Terraform was overwriting the Pydantic class Settings(BaseSettings) so S3_FILES_PRESIGN_TTL was being reset back to 600 and not being picked up as 3600 in the upload buckets.

I've changed the Terraform render.tf files to 3600 in this PR (ticket) for both the Sandbox and Prod environments. Would you or somebody else be able to check this out if you get a moment? I wasn't able to run tests/terraform plan/apply on this as I don't have the correct permissions/keys for Terraform.

Should have verified that it was completed yesterday, sorry about that! I have applied the terraform from your other PR now. It looks like it's working with longer file uploads now!

[obrienciaran]

Thanks for the approval. It was my fault for not double checking, I didn't realise Terraform overwrites config files like that.

I can confirm the signed URLs are now 1 hour for uploads on my end too.
