    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 ?

    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

    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"}

    for anyone else coming here,
    for me it was the same error and traced back to an error in the JSON schema in a Response step.
    Seems like no matter what, with this error go back and review whatever you modified in relation to any JSON related step that involves a schema.

    I solve the problem by creating new flow and copy/paste the content from old flow to new flow in the old version of flow editor.
