slack-file | Send a link to a file on a local network server

I am trying to hit an api(sample response) which gives list of objects and render it in a table in react. Following is my code. I am getting error as data is not defined

I have a scenario where the user uploads a PDF to the Slack bot. I fetch the URL from the Slack response and pass it to the base64 encoder. The encoder looks like:

I want to use a local file (image) in a block. As far as I know there is no way to use a local image in a message block directly, so I've decided to try to use a files.upload to first upload the image to slack and then use the link to that image in a block.

1. Upload image using files.upload
2. Get link for that image
3. Post a message block with the link to the image.

Problem is no matter what I do, I can't seem to get a valid link that I can then use in the message block. (All I get are "downloading image failed" errors).

I don't want the image to be publicly accessible. I want it to be only accessible to slack users logged into our slack workspace. So I need a link that my slackbot can use but not a public link.

Is there any way to do this?

I've already checked this related question and followed instructions there to try and get a link useable by my bot but I couldn't make it work.

Thank you very much for any help.

Block I'm trying to send: (for now I'm not dynamically building the link, just trying to do it manually till I get a link that works)

I have prepared a Sales recording form whereby you first select the product/stock_name. Once this selection is made it should populate a field called unit_selling price below with that product's/stock's price that should be fetched from the stock table in DB. This, happens partly since the the price of the first stock/product is fetched and only appears in the browser console. Help me fetch the specific product's price and make it appear in the form not only console. I have attached a DB pic.

I am trying to upload an image to slack and post it in an image block of a slack message to a specific channel.

1. upload an image to Slack.
2. make the image public with files.sharedPublicURL
3. check if the url is public: public_url_shared being true.
4. use the permalink_public I receive for the uploaded image for creating the slack message (an image block).

for debugging I am using Slack's Block Kit Builde. I am replacing the URL in the image_url example of the block kit demo with the one I received from slack:

I created a bot which collects info from users in a workspace. It stores this info in a csv file on the local server. How do I download said file? I got this bit of code from Stack Overflow, attempted to contact the author but didn't get any response.

I upload an image to slack using https://slack.com/api/files.upload not specifying channels field in the request. I can see the image in the web interface. What the api call should be to share the uploaded image in some channel at some point in the future?

I tried to upload an image and response from slack was:

My current project involves writing a script that makes an Excel file using Pandas and Xlsxwriter and sends this file through an email API on a schedule with cron. When generating the excel file on Windows during development, the format I initially set for the header works just fine.

However, when running the script through Linux during testing, the Header formatting disappears while the rest of the cells maintain their intended format.

I have included the code below to remove the initial header to use my own custom one
