Canvas Data 2 404 error on the data endpoint 'https://api-gateway.instructure.com/dap/query/canvas/table/' + $splitValue + '/data'

[hcollins]

I am able to call the schema endpoint, but I am getting a 404 error on the data endpoint

'https://api-gateway.instructure.com/dap/query/canvas/table/' + $splitValue + '/data'

The error is:

Failure: Failed to execute the request, or the endpoint responded an error, Reason: Got response 404 - Not Found from the endpoint, Resolution: Refer to the error document in the error view for more information

Does anyone have a suggestion on what to look for to correct the problem?

Thank you,

Heidi

What are you using to make this call?  And more importantly, what value does the variable $splitValue have?

The most likely scenario is that this value is null - which will generate a 404.

[hcollins]

splitValue is just a variable which contains the tablename, but if it were null I would not be able to get a successful call on the schema endpoint.

In that case, how are you generating the table names, and are you sure that they are all in the canvas namespace.  If using variables like that, you should have the namespace as a variable rather than just coding "canvas", as if your schema query is traversing multiple namespaces (such as catalog or the web-logs) then you may have tables from other namespaces.

Hi All.

This discussion was opened on my behalf and the 404 error turned out to be due to the fact that to get the data you use a POST, vs using GET like you do with the schema endpoint. After switching the /data endpoint to POST, the 404 error was resolved. I apologize for the mixup, I should have read the Postman collection a little more slowly.

Thanks,

James
