We're encountering an increased number of application errors in MySQL transformations. We're looking into this issue and will update this post once we know more. This may also affect GoodData writer jobs.
UPDATE Aug 21, 9:10pm PST
The error seems to happens randomly on all Storage API async exports from tables stored on Snowflake. We have contacted Snowflake support to help us identify the root cause of the issue.
You may encounter the error in any component that uses async exports from Snowflake or in any external integration exporting data from a Snowflake bucket. The error does not appear in Snowflake or Redshift transformations.
UPDATE Aug 22, 9:45pm PST
The error was not yet mitigated, Snowflake engineering team is looking into it. If you're encountering this problem, please contact us at support@keboola.com for a possible workaround.
We're sorry for this inconvenience.
UPDATE Aug 23, 5:24am PST
Snowflake engineers has identified a potential fix for this issue but it is not deployed yet. Meanwhile we have found the workaround for the issue and we are updating the components. GoodData writer was fixed now, transformation and other components will be updated within few hours.
This issue is happening randomly and less than one percent of exports were affected.
