java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0)
This exception occurs when there are fewer parameters specified in the SQL statement than the number of parameters being supplied.
For example, if the SQL statement has no parameters specified, but the Java code is trying to set a parameter using PreparedStatement.setXXX() method, then this exception will be thrown.
To fix this issue, make sure that the number of parameters in the SQL statement matches the number of parameters being supplied, and that they are in the correct order. Also, ensure that you are using the correct method to set the parameter value.
global obsensor_uvc_stream_channel.cpp:156 cv::obsensor::getStreamChannelGroup Camera index out of range
This error message indicates that the camera index specified in the code is out of range. The code is trying to access a camera that doesn't exist or has not been initialized, hence the index is invalid.
To resolve this issue, you need to check the camera index specified in the code and ensure that it matches the actual camera index. You can also verify that the camera has been initialized correctly and is available. If the camera index is correct and the camera is still not available, you may need to check the camera drivers or hardware connections.
