linkml2sheets doesn't work when given a directory of templates

[turbomam]

@putmantime and I have observed that running linkml2sheets on a directory of templates doesn't work, even when all of the individual templates do work

the linkml2sheets help gives this example:

linkml2sheets -s my_schema.yaml sheets/*.tsv -d sheets --overwrite

In the nmdc-schema repo, the following two work

schemasheets/tsv_output/slots.tsv: clean_schemasheets
	linkml2sheets \
		--schema src/schema/nmdc.yaml \
		--output-directory schemasheets/tsv_output/ \
		schemasheets/templates/slots.tsv

schemasheets/tsv_output/classes.tsv: clean_schemasheets
	linkml2sheets \
		--schema src/schema/nmdc.yaml \
		--output-directory schemasheets/tsv_output/ \
		schemasheets/templates/classes.tsv

but this doesn't work

schemasheets/tsv_output/all.tsv: clean_schemasheets
	linkml2sheets \
		--schema src/schema/nmdc.yaml \
		--output-directory schemasheets/tsv_output/ \
		schemasheets/templates/*.tsv

Even though

ls -l schemasheets/templates 

-rw-r--r--@ 1 MAM staff 71 Aug 16 17:22 classes.tsv
-rw-r--r--@ 1 MAM staff 58 Aug 16 17:26 prefixes.tsv
-rw-r--r--@ 1 MAM staff 2005 Aug 16 18:01 slots.tsv

The error is

Are you sure this is different from:

• linkml2sheets won't populate a prefix template, even if that template works with sheets2linkml when populated #70

what output do you get if the prefixes tsv is not in the directory?

[sierra-moxon]

closing as a duplicate of #70.

I think they are different issues and will write tests.
