API Response Timeout with a specific combination of request parameters

[Wei Wang]

Hello Experts, please help!

When trying to retrieve all the cards on a specific list A, it returns a 504 error (Response Timeout). However, I got a 200 response while sending the same GET request with other lists (e.g. list B and list C). There are 190 cards in total on list A, 166 cards on list B and 466 cards on list C. I am unable to reproduce this issue on other lists on the same board, neither any lists on other boards.

The endpoint that I am trying to call:

https://api.trello.com/1/lists/{id}/cards?key={api_key}&token={api_token}&filter=open&actions=createCard,commentCard&fields=dateLastActivity,desc,name,labels&attachments=cover&attachment_fields=fileName,url,date&sort=-id&limit=300&before=

The parameters included in the request:

• filter
• actions
• fields
• attachments
• attachment_fields
• sort
• limit
• before

In order to analyze the problem, I tried to test each parameters of the request and found the issue. The request can be successfully processed once I removed the parameter attachment_fields and sort. It also worked when I removed the input "commentCard" from the parameter actions.

Can someone please tell me if there is any problem with the request I wrote or what could be causing this?

Thank you in advance!

Best regards,
Wei
