@mjminfo: thanks for the reply and for the details on your setup.
I am still unable to replicate the error here. The log is useful to understand where the error occurred but not why; I can make some educated guess but nothing more, until I see the error happening under the debugger.
One guess I can make from the log is that, at a certain point, possibly near the beginning of the section (unfortunately, the log only has occasional time stamps), you had two copies of the GPS GUI open (or at least running, possibly one of them hidden in some way).
I do not understand how this can happen as, once one of them is on, it is not possible to access the chat and issue the "/gps" command again.
Does this ring any bell to you? Do you remember anything unusual or strange happening before you could start using the GPS GUI? Some chat command (apparently?) not responding?
A couple of questions:
1) I assume the sequence of individual steps was:
- issue the chat command "/gps"
- on the GPS GUI, press the "Next WP" arrow one or more times to access an empty WP slot
- press the "New WP" icon
- enter some text in the input box (incidentally, the text itself may have some relevance, do you remember it?)
- press ENTER
- ERROR message in the chat
Correct? Did I forget something?
2) does this error keep happening even after restarting the server or not?
I am sorry for these inconvenience; the whole matter is still in development and I appreciate your support to improve the matters.
