GLM Coding Plan - Frequent Errors

With GLM I am getting a regular "Invalid API Parameter. Check the documentation." as well as a timeout error. Both are frequent - and - I have to type "continue" to resume the activity. Not getting similar errors for other models. Should I be increasing some time interval somewhere? Just want to bring to your notice. This is more pronounced in 4.6 rather than 4.5

This issue might be a duplicate of existing issues. Please check:

AI_APICallError: The messages parameter is illegal. Please check the documentation. - Zhipu AI GLM-4.5 #2557: Similar GLM-4.5 API parameter errors with "The messages parameter is illegal. Please check the documentation." and requiring "continue" to resume
Opencode with GLM 4.5 String issue #1880: GLM 4.5 string/response data errors that cause opencode to stop working
No Response Requested #2892: GLM 4.6 "No Response Requested" errors and hanging issues
Timeout on "Updating plan" #2774: General timeout issues requiring "continue" to resume activity

Feel free to ignore if none of these address your specific case.

Hm this thread may be helpful (regarding api parameter issues): #2557

You can increase timeouts for a provider if you want:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "zai-coding-plan": {
      "options": {
        "timeout": 600000
      }
    }
  }
}

But generally I think the timeout is just the providers fault, if I notice requests hanging I like to double ESC then type "." and hit enter

yeah, I have just started getting tons of AI_APICallError: Invalid API parameter, please check the documentation. errors on GLM as well now, not sure the cause.

@ShamanicArts

@ShamanicArts which provider?

Z.AI Coding Plan

@rekram1-node

https://opencode.ai/s/X4oarVXT @rekram1-node

"zai-coding-plan": {
"options": {
"timeout": 600000
}
}

Zai-coding-plan seams to have problems with heavy traffic, I think, so editing provider ~/.config/opencode/opencode.json with this change works (at least for me).

@Rybens92

Thx for calling this out @Rybens92

Note: I do think Zai is having a lot of traffic and scale issues, I heard several people report outages today not sure if it relates or not

@rekram1-node

I tried that. Yeah, I think it's just traffic issue. For people who are also experiencing it, try what @rekram1-node suggested. Like do a nano ~/.config/opencode/opencode.json (save you a click, if you don't know where the config file goes), and paste that.

I am still having the error even with the timeout config. Just send a empty message . like @rekram1-node is good advice. Thanks for your messages here

Happy to help! any issues you have just lmk

yes, fully resolved for me, think it was just outage symptoms!

sweet

For people who are having the issue still, I think setting timeout helps, but the issue still persists. Likely the ZAI's side is experiencing heavy traffic

Hmm it if keeps happening we may wanna reopen this, this weekend I will get the subscription so I can start playing with it more and maybe encounter the issue

I have been running opencode with extreme usage via ZAI Coding Plan with glm-4.6 in the past few days, have not encountered this issue once.

I have had transient issues: 50x and rate limit issues (which 'Continue' resolves, or failing that starting a new session). #2892 is worst of all, because there seems to be no way of recovering.

Coming from a claude code perspective, it might help to have a retry configuration option on API failures?

Yeah we do have retries currently, need to figure out what is going on with 2892 tho

Reporting back, since I wrote that message 3 days ago. I haven't seen the issue again. So that's good news for me as a user 😀

Hi! I have frequent timeout errors using GLM models. Is there any way to solve this?

I have the same issue whenever i try to use the screenshot tool for playright mcp in opencode. I tried the timeout options suggested here that dod not do the trick... maybe should i clear opencode cache ? ...i have GLM-4.6 coding plan pro ... i did not go for max ... shouod i upgrade ... what is your experience with this issue ?
