Power Automate Desktop error: The request content is not valid and could not be deserialized: 'Unexpected character encountered while parsing value: %. Path '', line 0, position 0.'

 When you use "Invoke web service" action with URL that has special character "%", you can escape this character with "%%". But when you run, this error happens.

I got this error and I tried many methods. Only one method helped me to solve this. I turned the option "Encode request body" to Off in the Advanced setting of "Invoke web service" action.
