We are using the following command to deploy changes to SF org, and it works well:
But after we enabled Shield Platform Encryption,
https://help.salesforce.com/s/articleView?id=sf.security_pe_deterministic.htm&type=5, we are getting this error:
Indexed cannot be enabled for Deterministically encrypted fields without Unique - Case Sensitive attribute.

Any idea what's wrong?

I got this error from this command, any idea why?

Our SF admin has followed this to setup long time before:
https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_auth_jwt_flow.htm

Today they exported the private key to me, but I got this error running from a new Windows 2019 server:
  I found a cert on the org, seems not expired, not sure if its in the right place. I am a DevOps engineer, not SF admin.

Can anyone give me an idea how to troubleshoot this?

Thanks

Following the above steps, I am keeping on getting this error in running this command, any idea why? I am using free Developer edition online.

Is it possible to run Azure DevOps pipelines using Salesforce DX? Presumably the sfdx cli needs to be installed, but unsure of a starting point.

I've seen a video leveraging ANT scripts, but nothing so far with sfdx.

I am unable to successfully login using the Salesforce DX CLI. I have tried numerous techniques, all to no avail. In am on Windows 10 utilizing the latest version of the CLI from Powershell and Google Chrome as my web browser.

As a side note, the "sfdx update" command works successfully.

Technique 1. When logging in using what is supposed to be the easiest approach by using force:auth:web:login, the CLI opens a web browser. Once I enter my credentials, the OAuth flow calls back into localhost:1717, but apparently the CLI isn't listening. Chrome complains with an ERR_EMPTY_RESPONSE and no response payload. Command line indicates "Unable to verify the first certificate." Turning on logging (even at the trace level) does not reveal any additional information.

Technique 2. I created a self-signed certificate using openssl along with a new connected app. Then using the CLI, I utilized the force:auth:jwt:grant function. This failed with the same error message as above: "Unable to verify the first certificate."

Technique 3. I disabled SSL verification and strict SSL in npm and forced the CLI to go through Fiddler. I then configured Fiddler to ignore certificate errors. Still, neither one of the above techniques worked after this.

Any idea what I'm doing wrong?
