pandoc-citeproc: Error in $: Incompatible API versions: encoded with [1,21] but attempted to decode with [1,20].

MWE (using latest dev versions of pandoc and pandoc-citeproc, installed as described here):

pandoc -s -F pandoc-citeproc -t plain << EOT

Foo [@item1].

---
references:
- id: item1
  type: book
  title: The title
...
EOT

Output:

pandoc-citeproc: Error in $: Incompatible API versions: encoded with [1,21] but attempted to decode with [1,20].
CallStack (from HasCallStack):

This happens when you use a filter (in this case pandoc-citeproc) that is compiled against a different version of pandoc-types than pandoc.

Solution is to build them both at once. You can do that by cloning the pandoc repository and doing stack install pandoc pandoc-citeproc. Or just grab a nightly from the Actions tab; these contain both pandoc and pandoc-citeproc.

Meanwhile we should update the build info here.

I have the same problem with the following versions of pandoc and pandoc-citeproc:

pandoc 2.11
Compiled with pandoc-types 1.22, texmath 0.12.0.3, skylighting 0.10.0.2
pandoc-citeproc 0.15.0.1

I tried to build them both at once :

$ stack install pandoc pandoc-citeproc

Any idea how to solve this ?
thank !

pandoc-citeproc is no longer needed when using pandoc 2.11. See the changelog of that version.
