During testing of my firmware yesterday, I encountered the following error: Function myverylongfunction name not found Of course, I studied my C code for a while looking for the problem to no avail. I could not find the problem. I have three functions in my app, so I thought for some reason the P…

You are in luck! There is an Open Source version of the Particle cloud server. I can’t say for sure that the code in this version matches the hosted version most people use but since you feel so strongly about this and have a solution I would encourage you to submit a PR with your fix, maybe they w…

I don’t agree that there’s no way to do it in the cloud. Simply check the length of the function name that comes through. If it’s more than 12 characters, return an error. I can’t believe so much argument is being made about something that’s so very, very simple. If the limit is ever increased, chan…

[image] johnwargo: I don't agree that there's no way to do it in the cloud. Simply check the length of the function name that comes through. There is no name coming through, since Particle.function() fails to register it! This was clearly stated by multiple people in several posts.

Luke, All I’m trying to do is suggest a way to make this more seamless for developers. I really don’t appreciate the “this is costing Particle money, so you’d better like it or accept it.” I’m trying to help, I’m trying to share my experiences in an effort to make it easier for others to come up t…

The function name is on the end of the URL. Not rocket science to look at it, see it’s too long and reply.

You seem to miss the point. What do you expect your filesystem to tell you, when you ask it to cd /thisDoesNotExistNoMatterHowLongThisIs Do you expecti it to return, “This is no allowed directory” or “Not found”? There might be multiple reasons for the function name not existing, but “Not found”…

Okay, for the very last time… You put a function in your code. If the function name is <= 12 characters, the device registers it and submits it to the cloud. If the function name is >12 characters the device doesn’t register the function and it doesn’t get submitted to the cloud. The cloud can o…

OK, for the very last time… The cloud COULD check the length of the function it’s being asked to use and, if the length of the function name is more than 12 characters, it would know why it won’t be found and return a more useful response. That’s all I’m trying to say. Who cares how dumb the cloud …

I am not missing the point. The folder not found error in DOS is accurate because the folder doesn’t exist. In my case, I made the function, the device ignores it, so it’s not that it’s not found - it’s there, I just used a name that’s too long. That’s a COMPLETELY different problem.

First of all, I'm not opposed to improving anything, let that be clear. I just think this thread has gotten way more confusing than it ever needed to be. The cloud cannot check for function length on the device, since it has to be the device who tells the cloud what is and isn't there. [image] …

Woohoo! That’s exactly what’s needed, let them know it won’t work.
