Unexpected end of JSON input

[samuelpucat]

Description

I have a similar problem to issue #1933, I'm calling non-returning API defined like this.

generated schema.d.ts:

export interface operations { ... deleteLoadBalancer: { parameters: { ... }; requestBody?: never; responses: { /** @description OK */ 200: { headers: { [name: string]: unknown; }; content?: never; }; }; }; ... }

calling api:

const { data } = await client.DELETE('/load-balancers/{name}', { params: { header: { correlationId: generateCorrelationId() }, path: { name: loadBalancerName }, query: { projectId }, }, // parseAs: 'text', });

throws error:

SyntaxError: Unexpected end of JSON input at u (index.js:164:44)

which is in this part of library:

// parse response (falling back to .text() when necessary) if (response.ok) { // if "stream", skip parsing entirely if (parseAs === "stream") { return { data: response.body, response }; } return { data: await response[parseAs](), response }; // line 164 }

Calling the API with parseAs: 'text', solves the error but I don't know whether it is the correct solution.
I feel like this should have been caught by this part of code:

// handle empty content if (response.status === 204 || response.headers.get("Content-Length") === "0") { return response.ok ? { data: undefined, response } : { error: undefined, response }; }

but this API doesn't have Content-Length response header nor have 204 status

Question

Like I said, I would like to ask for advice, what would be the best approach:

• call the API with parseAs: 'text' flag
• change the API to return 204 status and Content-Length: 0 response header
• extend the openapi-fetch library to fail gracefully in case the response isn't possible to parse as JSON
