I upgraded my production environment to 1.8.0 but experienced issues with appwrite running out of worker threads. I downgraded back to 1.6.1 and restored the database, but now none of the functions work. I even tried redeploying the functions but receive the same error:
Could not resolve host: exc1 with status code 0
The existing functions that I didn't redeploy all terminate with the following error in the docker logs:
Iterating function: MyFunction
[Job] (694034106d28b9.28628715) failed to run.
[Job] (694034106d28b9.28628715) Could not resolve host: exc1 with status code 0
[Error] Type: Exception
[Error] Message: Could not resolve host: exc1 with status code 0
[Error] File: /usr/src/code/src/Appwrite/Platform/Workers/Functions.php
[Error] Line: 612
The .env and docker-compose.yml files are identical to the ones pre-upgrade, where the functions worked successfully.
I need an urgent steer as to what I can try because currently most of the functionality on my production instance is crippled.
TL;DR
Developers upgraded to version 1.8.0 causing worker thread issues, downgraded back to 1.6.1, but functions no longer work - receiving error "Could not resolve host: exc1 with status code 0". Tried redeploying functions but error persists. Existing functions also terminate with the same error in docker logs. Environment files are unchanged. Immediate assistance needed to restore functionality.
Potential Solution:
- Check DNS resolution for hostname "exc1"
- Ensure there are no typo or configuration issues in the updated version
- Revisit any changes made during the upgrade process that might be causing the issue
