What it means

A PipeDocGen step's template cannot be used to print its document.

What to do

Read params.finding, then fix the template, or the inputs the step maps into it.

Next steps

A problem carries the step aimed at whoever reads it: the first when its reader is the domain's actor, the method's author, and the second for any other reader.

Reader	Kind	Detail
The domain's actor	`change_method`	Fix the template '`{template}`', then run the method again.
Any other reader	`contact_owner`	Ask the method's owner to fix the template '`{template}`'.

Detail

The problem's detail is written from this template, filled with the occurrence's parameters:

The document template '{template}' cannot be used (reason: {reason}): {finding}

Parameters

Every parameter is present on every occurrence of the code.

Name	Type	Description
`template`	`identifier`	The template.
`reason`	one of `unreadable`, `does_not_fit`, `check_failed`, `value_unsupported`	Why it cannot be used: it is not a readable file of its format, it does not fit the step's inputs, it fails the engine's check, or it maps a value no cell can take.
`finding`	`caller_text`	What the engine found, about the method's own template.
