After i removed the extensionBundle section from host.json it started working for me.
Same issue for me :
I’m also experiencing this issue with the
v3
Functions runtime, and Java worker runtime.@anthonychu I don’t use extension bundles and don’t have
.azure-functions-core-tools
in my user folder.Here’s the output:
EDIT: This issue only occurs when I debug the function app through VSCode, but not when I manually trigger
func host start
…Work for me, have been deploy my app, hola! Thanks!
Any updates, I’m experiencing this upgrading from 3.1 to 5.0
