Honestly I feel like this is what I do, fill it with what they want to hear so I can progress versus actually discussing anything worthwhile because those things I bring uo at the time when it matters. 1-1 feels so pointless..
Like someone else said, a good manager doesn't want you to tell us what you think they want to hear; they want to hear the truth. If you can't trust your manager with work-related support, then that indicates other problems! Maybe it means your manager sucks, maybe it means you have past trauma with managers who couldn't support you, maybe it means that your company culture is toxic. But I view my 1:1 with my boss and my 1:1s with my reports to be some of the most valuable time at my job. I learn so much and it removes a lot of obstacles.
I've had bad bosses who don't know how to use 1:1s, and that means I have to do more work to make it valuable. I usually don't last long at those jobs, because I want bosses that make my job easier, not harder.
I've had reports that don't know how to use 1:1s, and it's incumbent upon me to teach them and ensure that they're getting maximum value out of it. If they aren't, then either I'm failing and I need to fix that, or they aren't interested, and I also need to fix that.
If you think your boss isn't hearing you or isn't someone you can trust and build a bond with and level up your career with, then but you either need to do some self-reflection or find a new boss.
There are other options, of course. You can keep your boss that you don't trust and get guidance elsewhere. Places like Rand's Leadership Slack or other tech hubs can be good places to get advice on how to level up in your career. There's a lot out there that you don't need to be chained to a boss whose 1:1s feel pointless.
I wish you the best of luck. Let me know if there's any way I can help.
That's the fault of your manager who hasn't framed it correctly, or who is not keen to do it themself (perhaps it is required for them as well!)
For me the key to good 1:1s is to build trust and to make clear that there is no such thing as "what I want to hear". I want to hear what you think and how things are going generally. And if there is not much to discuss them let's have a coffee and chat about the weather and holiday plans, that's good as well.
