Step 10 : Error: No image present. at _coerceRequest (/workspace/node_modules/@google-cloud/vision/build/src/helpers.js:54:25)

[shinkawa-shinji-japan]

Problem The code lab explanation uses "@google-cloud/[email protected]", but the latest version of cloud vision api was 2.3.0

I proceeded as "https://codelabs.developers.google.com/codelabs/firebase-cloud-functions" explains, but I got an error below.

Step 10 : Error: No image present.     at _coerceRequest (/workspace/node_modules/@google-cloud/vision/build/src/helpers.js:54:25)

how to resolve Here's are the code I modified and I could finally got it!

Comment out line is the github code. Not comment out line is the alternate code I wrote.

// const Vision = require("@google-cloud/vision");
// const vision = new Vision();
const vision = require("@google-cloud/vision");
const visionClient = new vision.ImageAnnotatorClient();

// const image = {
//   source: { imageUri: `gs://${object.bucket}/${object.name}` },
// };
const request = {
    image: {
    source: { imageUri: `gs://${object.bucket}/${object.name}` },
    },
};

// const batchAnnotateImagesResponse = await vision.safeSearchDetection(
//   image
// );
// const safeSearchResult =
//   batchAnnotateImagesResponse[0].safeSearchAnnotation;
// const Likelihood = visionClient.types.Likelihood;
// if (
//   Likelihood[safeSearchResult.adult] >= Likelihood.LIKELY ||
//   Likelihood[safeSearchResult.violence] >= Likelihood.LIKELY
// ) {
//   console.log(
//     "The image",
//     object.name,
//     "has been detected as inappropriate."
//   );
//   return blurImage(object.name);
// }
// console.log("The image", object.name, "has been detected as OK.");

visionClient
.safeSearchDetection(request)
.then((batchAnnotateImagesResponse) => {
safeSearchResult = batchAnnotateImagesResponse[0].safeSearchAnnotation;
const Likelihood = {
    UNKNOWN: 0,
    VERY_UNLIKELY: 1,
    UNLIKELY: 2,
    POSSIBLE: 3,
    LIKELY: 4,
    VERY_LIKELY: 5,
};
if (
    Likelihood[safeSearchResult.adult] >= Likelihood.LIKELY ||
    Likelihood[safeSearchResult.violence] >= Likelihood.LIKELY
) {
    console.log(
    "The image",
    object.name,
    "has been detected as inappropriate."
    );
    return blurImage(object.name);
}
console.log("The image", object.name, "has been detected as OK.");
})
.catch((err) => {
console.error(err);
});

I hope this help someone like me who will almost spend a lot of time to resolve this problem.

This definitely helped. Tutorials should always try to use the latest versions. Just a few things to add:

• This issue should be for Step 9 (at the time I'm writing this).
• You don't need to modify the safeSearchDetection function as an arrow function.

Here's the most basic fix imo:

//const Vision = require('@google-cloud/vision');
//const vision = new Vision();
const vision = require('@google-cloud/vision');
const visionClient = new vision.ImageAnnotatorClient();

...

//const image = {
//  source: {imageUri: `gs://${object.bucket}/${object.name}`},
//};
const request = {
    image: {
        source: { imageUri: `gs://${object.bucket}/${object.name}` },
    },
};

...

//const batchAnnotateImagesResponse = await vision.safeSearchDetection(image);
const batchAnnotateImagesResponse = await visionClient.safeSearchDetection(request);
const safeSearchResult = batchAnnotateImagesResponse[0].safeSearchAnnotation;
// const Likelihood = vision.types.Likelihood;
const Likelihood = {
    UNKNOWN: 0,
    VERY_UNLIKELY: 1,
    UNLIKELY: 2,
    POSSIBLE: 3,
    LIKELY: 4,
    VERY_LIKELY: 5,
};
