Is it possible that these network requests could be failing because the workflow is executing in a r

Is it possible that these network requests could be failing because the workflow is executing in a restricted region? I've heard of OpenAI blocking some regions, but I'd be surprised if Cloudflare's own AI product would also block.

I'm having a tough time figuring out another reason why these requests would fail so often. Maybe worth noting, but

get requests are ok for the most part, the requests that are failing are

Here's an example of the type of request I'm talking about.

      const generatedContent = await step.do("Write content", async () => {
        const ai = new OpenAI({
          apiKey: this.env.CLOUDFLARE_AI_TOKEN,
          baseURL: `https://api.cloudflare.com/client/v4/accounts/{my account id}/ai/v1`,
        });

        const result = await ai.chat.completions.create({
          model: "@cf/meta/llama-3.1-8b-instruct",
          messages: [...example]
        })

        return result.choices[0].message.content;
      })

      const generatedContent = await step.do("Write content", async () => {

Just to recap, and for reference if anyone face an identical issue, this was caused because the wrangler.toml file didn't contain the necessary

darrenOP•1/8/25, 10:41 PM

Sorry about bumping this one again, but I’m stumped.

Is there a way to see if I’m somehow bumping up against limits? The actual processing time shouldn’t be significant here. The network requests may be a bit slow, but from what I can gather from the docs, waiting on IO shouldn’t affect the limits.

Any insights or debugging advice would be appreciated.

Seekerdasbatatas•1/10/25, 6:42 PM

hey everyone, I've done on my free time a batteries-included library for Workflows called Flowcesinha: https://github.com/LuisDuarte1/flowcesinha

Custom storage engines and lazy step results (R2 included) so that, you can store more state inside of an step (and you can bring your own storage engine!);
Error reporting (Sentry provided in flowcesinha-sentry) and Workflow failure handler;
Reversable steps: ability to add a revert callback in case that the workflow fails;
Durable fetch: ability to fetch from APIs with dynamic retries (that come from the Retry-After header);
Functional primitives: doMap (map but every call is done inside of a step);
... more to come soon!

what would you guys want to see next?

hi team, I am struggling with creating/accessing database and service bindings for a workflow. Even though the bindings are defined in the wrangler.toml, the only binding that is accessible during the deployment is the workflow binding, DB and AGENT_LOOP are undefined.

wrangler.toml:
[[workflows]]
name = "wf-ainf-run-snap"
binding = "RUN_SNAP_WORKFLOW"
class_name = "RunSnapWorkflow"
main = "src/index.ts"
compatibility_date = "2024-01-01"
compatibility_flags = ["nodejs_compat"]

[[d1_databases]]
binding = "DB"
database_name = "ainfiltrators"
database_id = "xxxxx"

[[services]]
binding = "AGENT_LOOP"
service = "agent-loop"

deploy output:
Your worker has access to the following bindings:

Workflows:
- RUN_SNAP_WORKFLOW: RunSnapWorkflow

What am i missing here?
thanks in advance!

This looks like an issue with TOML inheritance. Try this wrangler.jsonwrangler.json instead:

Also note that for Service Bindings to work, you need to have a separate wrangler devwrangler dev running with the agent-loopagent-loop Worker

Thanks! Now I am struggling with calling one workflow from another. Is this possible? Both workflows are folders in the same monorepo. Let's say I want to call RunSnapWorkflow from RunEpisodeWorkflow. The things I have trouble with:

When I add the workflow_b binding to workflow_a wrangler.toml, i get a deploy error: "Your Worker depends on the following Workflows, which are not exported in your entrypoint file: RunSnapWorkflow. You should export these objects from your entrypoint, src/index.ts."
If i copy the RunSnapWorkflow class definition to RunEpisodeWorkflow, i can deploy. but when i call RunSnapWorkflow.create() "I get an error: Error: workflow.not_found "

I read through all the docs but i cannot find an example where one workflow calls another

Should i bind RunSnapWorkflow as a service and use fetch interface?

Matt Silverlock•1/12/25, 4:31 PM

Without your wrangler.jsonwrangler.json files it is hard to guess at what you are doing though. There’s nothing special here: make sure you are exporting each Workflow, and have a binding to the ones you want to call via the Workers API.

jordanfinners•1/14/25, 7:19 AM

Hey, I think I've got a bug.

Every so often workflows will fail to find the toISOString method on the WorkflowEvent.

timestamp.toISOString is not a functiontimestamp.toISOString is not a function

Which leads me to belive sometimes it's not parsing the event into a date object or losing that method somewhere.

Its failed 10 workflows for me overnight

jordanfinners•1/14/25, 9:18 AM

@Skye yes sure

export class ActionsWorkflow extends WorkflowEntrypoint<Env, StockTakeActionEvent> {
async run(event: WorkflowEvent<StockTakeActionEvent>, step: WorkflowStep) {
// some other code, but doesn't interact with event
const timestamp = event.timestamp.toISOString()
}
}

Is it possible that these network requests could be failing because the workflow is executing in a r
