OpenALPR Webhook Processor for IP Cameras

[mlapaglia]

possibly try that

 

[biggen]

I don't have a valid https cert for it.

 

[mlapaglia]

that's what the IgnoreSslErrors is for lol

 

[mlapaglia]

you should upgrade your watchman client to the latest also, there are big gains Release Notes — openalpr 2.8.101 documentation

 

[biggen]

Alright I'll give it another try with https when I get home and make sure that IgnoreSslErrors: true is set.

My Watchman is on the latest Docker version using the standard docker pull openalpr/agent. I wonder why they haven't promoted 2.8.101 to the latest?

 

[mlapaglia]

no idea, manually using openalpr/agent:2.8.101 works for me though

 

[mlapaglia]

ok, looks like there is one more step, on a fresh install a call needs to be made to create the "company" on the prem site.

 

[mlapaglia]

ok registration is in there now, you can remove CompanyId from appsettings, i figured out how to get it programmatically during registration. check the appsettings example username/password were adding to the openalprserver object.

 

[biggen]

Alright! I'll give it a try when I get home in a bit.

I must be missing something somewhere. Crashes on start. It may be because my Longitude is a negative number?? Edit: Nope. Changed Longitude to positive number and still crashed.

[mlapaglia]

make your endpoint "Endpoint": "http://10.200.200.54",

 

[biggen]

I edited the log. I actually had the /push/ in there before I noticed you had removed it in your new appsettings.json. Above is the new log without the /push at the end.

 

[mlapaglia]

yep, the url is used for multiple actions now, not just pushing, so it can't be /push anymore.

 

[biggen]

Ok. So the log above is valid when I start up the service using Endpoint": "http://10.200.200.54,. No /push. I don't have a < or > in the appsettings.json.

 

[mlapaglia]

you need a " after the 54

 

[biggen]

Here is my entire appsettings.json:

[mlapaglia]

you need a } at the end of your file. plug your json into Best JSON Formatter and JSON Validator: Online JSON Formatter and click "format / beautify" it will tell you what's wrong.

 

[mlapaglia]

This might be an issue with the response when it tries to register..

 

[biggen]

Its there. I just missed it when I copy-pasted.
