Redshift source "Failed to fetch schema"

  • Is this your first time deploying Airbyte?: No
  • OS Version / Instance: Ubuntu VM / GCP n1-standard-2
  • Memory / Disk: 2 vCPUs, 7.5 GB memory
  • Deployment: Docker
  • Airbyte Version: 0.39.35
  • Source name/version: Redshift 0.3.14
  • Destination name/version: BigQuery 1.1.11
  • Step: Fetching source schema
  • Description: Redshift data source fails to load schema

Hi! I am trying to set up a Redshift data source. The source test connection succeeds, but when I try to create a connection with it, I get the error message “Failed to fetch schema. Please try again”, and I don’t know how to troubleshoot further. I know the user I am using has read permissions on the cluster/database/schema I am trying to connect to.

What steps can I take to try and figure out what is going on? Would it help to temporarily increase the size of the disk running our Airbyte server? What does it mean when a Redshift data source tries to fetch a schema and fails without explanation after a few seconds?

Hello there! You are receiving this message because none of your fellow community members has stepped in to respond to your topic post. (If you are a community member and you are reading this response, feel free to jump in if you have the answer!) As a result, the Community Assistance Team has been made aware of this topic and will be investigating and responding as quickly as possible.
Some important considerations that will help your to get your issue solved faster:

  • It is best to use our topic creation template; if you haven’t yet, we recommend posting a followup with the requested information. With that information the team will be able to more quickly search for similar issues with connectors and the platform and troubleshoot more quickly your specific question or problem.
  • Make sure to upload the complete log file; a common investigation roadblock is that sometimes the error for the issue happens well before the problem is surfaced to the user, and so having the tail of the log is less useful than having the whole log to scan through.
  • Be as descriptive and specific as possible; when investigating it is extremely valuable to know what steps were taken to encounter the issue, what version of connector / platform / Java / Python / docker / k8s was used, etc. The more context supplied, the quicker the investigation can start on your topic and the faster we can drive towards an answer.
  • We in the Community Assistance Team are glad you’ve made yourself part of our community, and we’ll do our best to answer your questions and resolve the problems as quickly as possible. Expect to hear from a specific team member as soon as possible.

Thank you for your time and attention.

Maybe, open the network tab to get the API response and see if there is better error explanation there.
Other solution is to create a test user with only one table access and see if it is able to catch the table.
How many tables this database has?
