Issue with HTTP Trigger after updating to the new URL

Posted on by AA-02011229-0

Hello there!

In the previous version, I was using the HTTP trigger to handle a query parameter. But with the new URL, I'm sending my query data, and the flow can't interpret it.

When I test the new URL, I can see the header "x-ms-igw-external-uri" with a uri, and my query data appears at the end.

Does anyone have the same problem? Any possible solution?

Hi @AA-02011229-0,

Yes, I have been also able to reproduce this issue and reported this to Microsoft as well. Will keep you posted about my progress.

Btw, interesting that you see the data in that header x-ms-igw-external-uri property. That might give you an option to extract it with a couple of split functions in an expression as a temporary workaround until it is fixed.

I just hit the same issue. Appended "&phone=+15554441234" and when calling the new URL and received this error:

Action 'Initialize_phone' failed: Unable to process template language expressions in action 'Initialize_phone' inputs at line '0' and column '0': 'The template language expression 'substring(triggerOutputs()?['queries']['phone'],sub(length(triggerOutputs()?['queries']['phone']),10),10)' cannot be evaluated because property 'phone' cannot be selected. Please see https://aka.ms/logicexpressions for usage details.'.

Works fine with the old URL. Bad enough they changed all the flow URLs, but breaking functionality at the same time makes this a bit of a nightmare.
