fpt syntax check isn't giving me enough information to find error

[mdlopresti]

When running the fpt command to check syntax of a policy template it is telling me there is a syntax error, but it doesn't say where. Also when uploading to the flexera goverance page, I don't get a syntax error and I can execute the template. Below is my output.

fpt check ./azure_tag_missing_sysid_all.rb --debug
Checking ./azure_tag_missing_sysid_all.rb
An unexpected error occurred: missing token
ERROR: compilation errors occurred

Attached is the Dockerfile that defines the dev enviroment I am working in and a sanitized version policy I am trying to check, for ease of replicating the error.

My end goal is to use FPT for a CI process tool and if possible a linter in vscode.

What version of fpt are you using? With the latest version (v1.2.2), I am getting this:

Checking .\azure_tag_missing_sysid.rb
1 syntax error found:
  origin: template: azure_tag_missing_sysid.rb, line: 336
  problem: Syntax error
  summary: unexpected end-of-input, expecting keyword_end.
  resolution: Use valid Policy Template syntax. More information at http://docs.rightscale.com/policies/reference/v20180301/policy_template_language.html#syntax

ERROR: compilation errors occurred

Looking at the source I figured out that there was a missing end on your policy block:

         end
     end
   end
+end

With that change, it looks like your policy is accepted by fpt check.

After checking it looks like (v1.2.2), each time the container restarts it is downloading it from https://binaries.rightscale.com/rsbin/fpt/v1/fpt-linux-amd64.tgz

fpt -v
fpt v1.2.2 - 2021-01-15 19:59:42 - 756b1e0749b6458539d13945098deebe0c0dfe68

From your slashes are you using the windows version?

[douglaswth]

I have tested it on both the Linux and Windows versions and get the same results that I mentioned on both.

Looking at where the "An unexpected error occurred:" error comes from, it looks like it is probably getting something unexpected back from the Policies system rather than being something wrong with fpt itself.

It might make sense to contact support about this issue.

I was on a call last night before hoping off for the day with @rshade and he was telling me the same thing. I'm going to polish up a way of easily reproducing the issue, then contact support.
