Hi @netflash, Thanks for your bug report.
This problem seems to be occurring in external packages. I have released v0.4.1, which updated the external packages to the latest version. Please try this.

not sure if I need to attach anything else to help debugging this

Please use --debug options :)

[netflash]

Thanks, @wata727.
Still doesn't work (version updated)

make: *** [lint] Error 2

[wata727]

Umm... It seems to be occurring when evaluating the attributes of a module. But I don't know how to reproduce it.
If there is a module that uses interpolation syntax in the templates, can you show it?

[netflash]

@toddmichael hey mate, need some assistance here.
how can I share that module ?

[toddmichael]

@netflash, not sure which module, but I'm generally fine provided nothing sensitive (and there shouldn't be). Are we talking about just sharing for debugging purposes or do we need to open source the module and make public? Even there, this is something we're working toward so it's worth it to prioritize if it helps @wata727 help us.

[sidick]

I had the same issue, I narrowed it down to where I'd set a variable to "default = 1" and then was using it as "${var.name}" with quotes. That would explain the "is int not string" error message. As soon as I changed the default to be "1" rather than 1 it didn't crash

[wata727]

Oh... Thanks, @sidick. I noticed that I had made a very basic mistake.
I will fix this problem soon. please wait a moment.

[wata727]

@netflash @sidick I've fixed this bug and released v0.4.2. Please try again.

[netflash]

Problem sovled, thank you!

[sidick]

Yep, fixed here too, thanks
