Trying To add Flow to Power Apps but getting Error WADL

Hi there,

 

i createt a flow for my Power Apps and added it to my App. First everything was fine but after i removed and added it again an Error occured.

 

Error Message:

 

The flow input and output schema cannot be represented in WADL.

 

 

I have no idea what the Problem is. Could anybody help?

 

Thank you

So i found my problem.

I fetched data dynamicly from Sharepoint and interpreted it width JSON. In the JSON Schema i had the point jobtitle and it often returned null because my campony doesn't have a jobtitle for every employer. I tried to use a different method than deleting the type from the jobtitle and used array of types where i included "null".

After i removed this part i can now integrate the flow in my power app.

 

Have a nice day

Thank you for your fast answer 🙂

 

I found this link before but it didn't help. I don't pass an Array to my Flow. I use the Power Apps V2 Input to pass only one string parameter to my flow. The Flow is using the response function to return width http.

 

Do you have an other Idea how to solve the problem @Nogueira1306 ?

I had same

 

initially, my schema was {} for a nullable field. like "field":{}

So I changed to "field":{"type":["string","null"]} because my field may accept string.

once I left just "string" it started to work for me, like "field":{"type":"string"}
