How does a WebJob work in Azure?

Augusto Navarro 20

I need to understand how to configure a WebJob, I registered a new one, with an .exe file, which I generated from a .Net project. the file has the function of consulting an api and sending emails. When the webjob is executed, it shows me the following error:

[08/24/2023 13:30:00 > 80300b: SYS INFO] Status changed to Initializing

[08/24/2023 13:30:00 > 80300b: SYS INFO] Run script 'MwHealthCheck.exe' with script host - 'WindowsScriptHost'

[08/24/2023 13:30:00 > 80300b: SYS INFO] Status changed to Running

[08/24/2023 13:30:04 > 80300b: ERR ] The application to execute does not exist: 'C:\local\Temp\jobs\triggered\MvHealthCheck\silaw3hz.few\MwHealthCheck.dll'.

[08/24/2023 13:30:04 > 80300b: SYS INFO] Status changed to Failed

[08/24/2023 13:30:04 > 80300b: SYS ERR ] Job failed due to exit code -2147450726

I don't know where to find the directory

Hi Augusto,

Looking at the error you received it seems one of the files for your application is missing. Did you publish your WebJob using Visual Studio? The publish step will upload necessary files to Azure.

Recommend you walk through article below:

Develop and deploy WebJobs using Visual Studio

in the first part I did it from the Azure portal, now I did it from VS and it no longer shows me that error, it shows me another one:

[08/24/2023 14:38:09 > 80300b: ERR ] Unhandled exception. System.IO.FileNotFoundException: The configuration file 'appsettings.json' was not found and is not optional. The expected physical path was 'C:\local\Temp\jobs\triggered\MwHealthCheck\xmposy1y.mvw\appsettings.json'.

Seems like your zip doesn't contain the appsettings.json. Right click on Properties for that file in VS and make sure Copy to Output Directory is set to either Always or Copy if Newer.

See here for information on the folder structure of web jobs.

I had to create the .zip manually and upload it to azure manually, but it seems to work. thank you so much
