Error "toml: incomplete number" but only on init command, not on execute-template

[halloleo]

I have written the following (shortened) .chezmoi.toml.tmpl (in my custom git repo location ~/Dropbox/sync/chezmoi/):

{{- $hostname := .chezmoi.hostname -}}
{{- $sysname := "unknown" -}}
{{- $sysgroup := "unknown" -}}

{{- if eq .chezmoi.hostname "host-A" }}
{{-   $sysname = "work-host" -}}
{{-   $sysgroup = "datavol" -}}
{{- else if eq .chezmoi.hostname "host-B" }}
{{-   $sysname = "drop-1" -}}
{{-   $sysgroup = "dropbox" -}}
{{- else if eq .chezmoi.hostname "host-C" }}
{{-   $sysname = "drop-2" -}}
{{-   $sysgroup = "dropbox" -}}
{{- end }}

{{- if eq $sysgroup "dropbox" }}
sourcedir = ~/Dropbox/sync/chezmoi
{{- end }}

# Now the standard data variables:
[data]
    hostname = {{ $hostname | quote }}
    sysname = {{ $sysname | quote }}
    sysgroup = {{ $sysgroup | quote }}

This generates the expected output via

cz execute-template  < ~/Dropbox/sync/chezmoi/.chezmoi.toml.tmpl

but when I run

cz init -S ~/Dropbox/sync/chezmoi

I get the error "chezmoi: ~/Dropbox/sync/chezmoi/.chezmoi.toml.tmpl: toml: incomplete number".

What is going on? What is going wrong?

Thanks for any pointers!

ps: I run these commands on machine "drop-1", i.e. with the git repo in custom location.

The syntax of your generated TOML is not correct. You have to quote strings.

Ahhhh, I see! That makes total sense. Will check the resulting file closely.

[halloleo]

Yes, that was it! I had forgotten to quote the sourcedir value... 😵

Is there a way to troubleshoot these problems on the machine with some debugging? (I had tried cz --debug init -S ~/Dropbox/sync/chezmoi but this does only give detailed information about the stages before the toml file gets parsed...)

chezmoi execute-template --init < .chezmoi.toml.tmpl | taplo lint

If you have prompts you probably want additional flags, and I think I got the taplo sub command right, but I'm on my phone. You will of course require taplo or some other TOML linting/formatting toolkit.
