I tried to switch to preview Azure App Service Webjobs running on linux for nodejs continuous webjob without luck.
(I have deep successful experiences on nodejs/C# ones on AppService Webjobs running on windows).
The beginning is promising, but for unclear reason, the error message refers to node.exe

Tried to play with an extra “script.sh” inspired from this site with no success.

#!/bin/bash
node run.js
stack correctly on nodejs 20
enabled SCM Basic Auth
worth noting, the script runs fine if directly instancied from ssh within the appservice (xxxxx.scm.azurewebsites.net/newui/webssh)
Tried deployment via
- ftp
- zip deployment
- directly playing through ssh/vi/etc
run.js (simplied a bit ;))
console.log("I'm alive");
script.sh
#!/bin/bash
/opt/node-wrapper/node run.js

I created a sample Node.js WebJob script, zipped the script file, and uploaded it to Azure WebJobs.
ERR ] An error occurred trying to start process ‘node.exe’ with working directory ‘/home/site/wwwroot/App_Data/jobs/continuous/test3’. No such file or directory
The above error occurred because of naming convention in web jobs.
- When you name the file
run.js, the WebJob considers it as an entry point, and it can cause errors. - I got the same error when I used file name as run.js, so to avoid the error I’ve changed file name
run.jsto any other name likeindex.jsorserver.js. - As mentioned in comment, if you want to use the file name
run.js, then you should also change the.shfile name torun.shto ensure it works correctly.
My script .sh:
node run.js
I can successfully see the Azure web job logs without any errors.
