Hi All,
I am getting an error when trying to add a Flow. The error message says 'The flow input and output schema cannot be represented in WADL. code: FlowWadlConversionNotSupported'
I actually updated an existing flow to allow PowerApps to pass one extra parameter. I got an error when refreshing the existing flow. The error message is 'The flow input and output schema cannot be represented in WADL.
code: FlowWadlConversionNotSupported' . This is the reason I created a new flow.
The new flow was created by clikin on 'Add new' in the power app maker. It did work initially and srated throwing hte error when I made update to parse JSON. I have removed the JSON parsing part and the error is still there.
Did anyone have similar issue?
Thanks,
Thank you! I faced the same issue. It threw the error after I used a real query to generate the schema. It left out the data types for a couple of fields. After a filled in Type: "integer" for each of them, the error went away.
Hello,
A quick way to fix thix error
When generate your Schema, at the end you will find some require Paremeter, if thoses parameters are empty in your Json, this will cause this, you can get rid of those parameters in the require section of your Schema, then your flow will be added to Power Apps (See attached picture)
This didn't fix it for me, I added the null handling, and I was able to refresh my object in Power Apps, but it lost the schema in the app. I had to go back and remove all null handling and just have the types specified and it started working.

Thanks Todd-fraser. My issue was similar, I had some properties with {"type": ["string","null"]}, was solved by forcing it to string only.
This is the way. Thanks! I had multiple ones missing data type.
this saved me! thank you!!
If you want to send me your schema to take a look at, I'll see if I can find anything.
same happens to me
Thank-you so much. Wish I would've come across this answer an hour ago.
