An error with the HTTP Status 400 – Bad Request has been encountered while trying to access a webpage, with the message stating that an invalid character was found in the request target. This error indicates that the server is unable to process the request due to a perceived client error such as malformed request syntax or invalid request message framing.
The exception report shows that the issue is caused by an invalid character found in the request target, with the valid characters being defined in RFC 7230 and RFC 3986. The error message identifies the specific line of code within the org.apache.coyote.http11.Http11InputBuffer class where the issue occurred.
The server uses Apache Tomcat/8.5.45, and the full stack trace of the root cause is available in the server logs. This error can disrupt the user experience and prevent access to the desired webpage.
To resolve this issue, developers may need to review and adjust the request syntax to ensure that it conforms to the standards outlined in the RFC documents. By correcting the invalid character and ensuring that the request message is properly framed, the server should be able to process the request successfully.
Overall, encountering a HTTP Status 400 – Bad Request error can indicate issues with request syntax and message framing, requiring developers to address these issues to ensure smooth access to webpages.
