Projection Error #132

Closed ES5017 closed 5 years ago

ES5017 commented 5 years ago

stitch query failed with error serviceError(withMessage: "invalid %project specification: projection string value must start with a \'%\': {\"pendingRequestsSent\":{\"$elemMatch\":{\"firebaseUserId\":\"AQym4EGUgMOhwUFbp1LASJwyYlN2\"}}}", withServiceErrorCode: StitchCoreSDK.StitchServiceErrorCode.invalidParameter)

This is not mentioned anywhere in the docs. Printed query looks like this:

{ "pendingRequestsSent" : { "$elemMatch" : { "firebaseUserId" : "AQym4EGUgMOhwUFbp1LASJwyYlN2" } } }

Copied and pasted into mongo shell projection parameter, and it works fine.

Hi @ES5017 I see that you were able to get more clarity on this issue through our Gitter (https://gitter.im/mongodb/stitch). I will close this issue for now. Please open a new issue if you have any further problems using the SDK!

For anyone who also experiences this issue, the problem is that this is a projection feature that is currently unsupported via MongoDB Stitch. Adding support for all the projection features is on the roadmap for the next month or so.
