CosmosDB NodeJS SDK query Timeout

Jason Ortiz 1

Hello,

I am having an issue with a timeout using the Cosmos NodeJS SDK within an async Azure function (HTTP Trigger). I followed the tutorial found here to build the same example. Is this an issue with the async flow or the Cosmos connection? My code is a copy and paste of that example with my own database configs of course.

For the life of me I cannot figure out how to post my code here without getting the WAF error mentioned in the Announcements. IF anyone knows how to fix that, I will post my code snipped as a follow up.

Please Note: I cannot use an input binding as the parameters for the query I am trying to perform are determined dynamically by the function itself and not passed in as an HTTP request parameter.

Thanks for writing to us.

I tried using the same node.js SDK mentioned in the article and I was able to successfully query the database for all operations.

Could you please provided the code snippet used by you to further look into the issue?

Hi Anurag,

Thank you for replying. I am having trouble including code in my posts (I always get the WAF error mentioned in the announcements) but I was able to attach it here. The context.log for the queryspec works but the very next line times out. Thank you for your help!

I just wanted to nudge this thread with a little more information. I was able to produce an error message by modifying my timeout to be much shorter than the default 5 minutes. The code above produces this error:

Cannot read property 'replace' of undefined

I do not use replace anywhere in my code, so I am assuming it must be used somewhere in the azure/cosmosdb library. I am not sure what this would indicate. My query is just to select * from c so elements should be returned, the database definitely exists and I double checked all the keys, ids etc.

Any advice or help is immensely appreciated!

Thank you,
Jason
