    From document System.InvalidOperationException class, we could know that

    InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. Typically, it's thrown when the state of an object cannot support the method call.For example, an InvalidOperationException exception is thrown by methods such as:

    I couldn't see other codes, but you can first recheck the document above. If you still haven't found the problem, could you please share the code snippets and give an overall problem description of what you are trying to accomplish?

    Hope you are doing good! Thank you for reaching out. Please find the answer below.

     

    You're encountering a System.InvalidOperationException while trying to process a request in your PaymentController. This exception typically occurs when the state of an object does not support the method call being made.

     

    1.Code Review: Check the method ProcessRequest() in your PaymentController.cs file, specifically around line 18883190814. Look for any conditions where an object's state might not be valid to perform the desired operation.

     

    2.Collection Modifications: If you're iterating over a collection (like a List or Array), ensure you're not modifying the collection while it's being enumerated.

     

    3.Threading Issues: If you're manipulating UI elements or shared resources accessed from multiple threads, make sure that these interactions happen on the appropriate thread (typically the UI thread).

     

    4.Error Code Context: You mentioned the error code <error_code_> 18883190814. Make sure to check if this is logged or detailed elsewhere in your codebase to provide more context on why it's thrown.

    5.Inspect ProcessRequest() Logic: Look for any conditional logic that assumes a non-null or initialized object.
    Check for any asynchronous operations that might not have completed before the method proceeds.
    Validate that all dependencies (e.g., services, clients) are properly injected and initialized.

     

    6.Review API Response Handling: Log the raw response from the API before parsing.
    Ensure the response schema matches what your code expects.
    Add defensive checks (e.g., null checks, schema validation) before accessing response properties.

    Here are some follow-up questions to help better understand the issue:

    1.Can you share the specific code snippet where the ProcessRequest() method is implemented? 2.What conditions typically lead to this InvalidOperationException in your context?
    3.Are there any specific actions leading up to this error that you've noticed? 4.How are you calling this method? Are you passing any parameters that might impact the object's state?

     

    If issue still persist after following the steps, we’ll be happy to assist further if needed." Kindly mark the answer as accepted if the issue resolved".

    the invalid operation means the controller action could not be called. typically the post or query string data is invalid or missing.
