Most common errors and pitfalls

This guide will describe the most common OTTR errors and pitfalls and how to address them.

Finding info about errors:

When you open a pull request, you should see a report like this:

When you see an ❌ , click on the Details button to see the error message. We'll discuss the most common error messages here.

Google slides permissions fail:

Error example:

Error in png::readPNG(path, native = TRUE, info = TRUE) : 
  file is not in PNG format
Calls: local ... lapply -> FUN -> raster_dpi_width -> attr -> <Anonymous>
Execution halted
Error in Rscript_render(f, render_args, render_meta, add1, add2) : 
  Failed to compile <file_name>.Rmd
Calls: local ... <Anonymous> -> render_new_session -> Rscript_render
Execution halted
Error: bookdown::render_book() failed to render the output format 'bookdown::gitbook'.
Execution halted

What does this mean?:

Your Google Slides presentation you have tried to retrieve a slide from with ottrpal::include_slide() is not public. Your Google Slide document must be set to Anyone with a link. See this article for more details. The renders will fail if this is not set! See the setting up images and graphics section for more details.

Spell check/url check/quiz format fail:

Underneath a section that says something like: **Check spelling/url/quiz errors - fail if too many of them** you may see something like:

Run exit 1
  exit 1
  shell: sh -e {0}
Error: Process completed with exit code 1.

This is failing on purpose -- it means that checker has found errors. Return to your pull request page and look for a comment that says something like:

⚠️ There are <spelling/quiz/url> errors that need to be addressed. Read this guide for more info.
Download the errors here.
Comment updated at <some_date> with changes from <commit>

Merge conflict fail:

Error example:

CONFLICT (modify/delete): <file_name> deleted in <branch_name> and modified in HEAD. Version HEAD of <file_name> left in tree.

This will often happen when render-preview's git handling doesn't know which changes you are looking to preview. easiest way to fix this problem is to create a separate pull request that completely deletes the files lists. To do this, follow these steps:

1. Take note of your pull request's number. Go to the pull request page and see what #number is posted there.
2. On your GitHub repository, go to Code and click on Branches.
3. Your pull request's preview is made on a branch named preview-<number of your pull request> . Find this branch and click the trash can icon. This will delete the preview branch and hopefully get rid of this error. Read this for more info on how to delete a branch.
4. Re-trigger your GitHub actions run and it should pass.
