            Remove colon in figure caption using pandoc and bookdown in R Markdown

            I am changing the font of a figure caption in my R Markdown and am using bookdown and pandoc to do so. My question is closely related to: How to change the figure caption format in bookdown?. I was able to get correct figure numbering and was able to alter the format of the "Figure 1" portion of the caption. However, I cannot figure out how to remove the colon in the output (i.e., "Figure 1:. ").

            Looks like there was a change in rmarkdown which adds a colon by default. Also the reason why the answer in the linked post does not work anymore. For more on this and a solution see https://community.rstudio.com/t/how-to-change-the-figure-table-caption-style-in-bookdown/110397.

            Besides the solution offered there you could achieve your desired result by replacing the colon by a dot. Adapting the lua filter provided by https://stackoverflow.com/a/59301855/12993861 this could done like so:

            Elastic Beanstalk environment is failing suddenly. Why?
            Asked 2022-Jan-27 at 17:18

            I am at a complete loss and really freaking out, because this project of mine was close to being done. I will give out a bounty for the answer that helps me (when I can). I am desperate, please help.

            I have an Elastic Beanstalk project that has been working fine for literally months. Today, I decide to enable and disable a port listener as seen in the photo below:

            I enabled port 80 and then the website stopped working. So I was like "oh crap, I will change it back". But guess what? It is still broken. The code has not changed whatsoever, but the application is now broken and I am freaking out.

            I have restarted the app servers, rebuilt the environment and nothing. I can't even access the environment site by clicking Go to environment. I just see a Bad Gateway message on screen. The health status of the environment when first deployed is OK and then quickly goes to Severe.

            If my code has not changed, what is the deal here? How can I find out what is going on here? All I changed was that port, by enabling and then disabling again.

            I have already come across this question: Question and I am already doing this. This environment variable is on my application.properties file like this: server.port=5000 and its been like this for months and HAS ALREADY been working. So this can't be the reason that it broke today. I even tried adding it directly to the environment variables in Elastic Beanstalk console and same result, still getting 502 Bad Gateway.

            I also have a path for the health-check configured and this has not changed in months.

            Here are the last 100 lines from my log file after health status goes to Severe:

            Asked 2021-Dec-22 at 13:36

            I am trying to solve a BVP problem (Cosserat rod ODE) with gekko. The goal is to find the initial conditions nsol and msol (which correspond to the internal forces and moments of the rod) that minimize the cost function (the position of the final point of the rod), when integrating, the cosserat equations gives us P, R, nsol, msol, which correspond to the position, orientation, internal forces and moment in a section of the rod.

            but I keep getting this error:

            Exception: @error: Equation Definition Equation without an equality (=) or inequality (>,<) false STOPPING...

            For now you can't invoke a SAM lambda locally with X-ray because it is not supported yet.

            See

            The component does not support X-ray and other Lambda integrations locally.

            If you don't care about X-ray and just want your code to work you can check the env variable AWS_SAM_LOCAL to prevent X-ray usage:
