I encountered a similar issue. When attempting to scan text for AI content, I received an error message that said "Failed to Detect String content at GptZero:[object Object]". I decided to skip that step and proceed directly to "Humanize Content". However, I then received another error message stating, "Error:{"message":"Request failed with status code 500","status":500,"data":{"error":"Internal server error"}}". I tried this approach but it did not work. I logged out, cleared my browser cache logged back in, & tried again, but I continued to receive the same error messages. I logged out once more and tried with different AI-generated text and a different web browser, but I encountered the same errors. I reached out to support and the only part that was fixed is the AI detect but humanized still shows same error.
