Flow API name is missing

[swayingpalm]

Followed all instructions in VS Code and SFDX.
Entered: sfdx flowdoc:pdf:generate

Receiving the following error:
running flowdoc:pdf:generate: Flow API name is missing

Org is connected, API names have been verified. I can successfully query Objects.

What am I missing?

I have the same symptom as you.
Someone in the the comments on the Creator's page also.
I tried all combinations of commands.
sfdx flowdoc:json:display
sfdx flowdoc:docx:display
sfdx flowdoc:pdf:display
sfdx flowdoc:json:display
sfdx flowdoc:docx:display
sfdx flowdoc:pdf:display

with many possible ways to provide the args file.
with --file PROCESS_NAME (undocumented, but the code let me think that could have worked)
PROCESS_NAME
./PROCESS_NAME

tried running the command in the subfolder were the process is.

MAybe i'll trry to "hardcode" the process name as a test.
BUt that means I'll need to figure out how to repack the plugin.

Just letting you know that your are not alone.

Hi, I think this plugin is no longer maintenance ?
I have the same issue with Flow API name is missing and no update since 4 years.
