Error 404 - "Cannot read server response." - "The response is not in a JSON format."

Hey all!

In my flow I'm receiving list of environments as admin.
After that I'm receiving list of flows as admin applying to each environment from the previous step.
For a year the flow was working fine but now it's failing in action list of flows as admin with following error:
  "error": {
    "message": "The response is not in a JSON format.",
    "innerError": "Cannot read server response."
The pagination of this step is turned on. This error is disappearing after the turning off the pagination. And I can't understand what happened because it worked fine with pagination "on" and I need this pagination.
Maybe someone knows how to fix this please? It would be great!

Thanks in advance!

Hi All, 


I am getting the same thing here.  Trying to get the full list of flows in our environment.  With pagination off, and the 'Top Count' set to 250, i get 250 flows returned.  Once pagination is turned on and set to any value, it throws the JSON error.  Using pagination is what this post from a couple of years ago suggested with evidence that it worked once upon time maybe?  Solved: How to get a list of all flows in environment - Power Platform Community (


Any help out there would be greatly appreciated as we are trying to get a handle on what is all out there.
