Describe the bug

I'm using strapi-provider-upload-azure-storage plugin with the new version of Strapi v4.2.0 that allows you to update a custom logo in the Strapi Dashboard and I was struggling with a response error 500 from Strapi in the Dashboard.

Please take a look inside the Chagelog ( https://strapi.io/blog/announcing-strapi-v4.2 )

I found a Workaround to fix this issue! 🚀

This is the Strapi Console error:

Code snippets

At this point I implemented this code inside the file located in this path ./src/index.js:

1. I created a function for converting a Stream to a Buffer with this code:

function stream2buffer(stream) {
  return new Promise((resolve, reject) => {
    const _buf = [];

    stream.on('data', (chunk) => _buf.push(chunk));
    stream.on('end', () => resolve(Buffer.concat(_buf)));
    stream.on('error', (err) => reject(err));
  });
}

2. I implemented this code before runs the application inside the bootstrap:

bootstrap({ strapi }) {
    /**
     * Temporary workaround for strapi-provider-upload-azure-storage
     */
    strapi.plugins.upload.provider.uploadStream = async (file) => {
      file.buffer = await stream2buffer(file.stream);

      return strapi.plugins.upload.provider.upload(file);
    };
  },

This is the all code in the context:

'use strict';

function stream2buffer(stream) {
  return new Promise((resolve, reject) => {
    const _buf = [];

    stream.on('data', (chunk) => _buf.push(chunk));
    stream.on('end', () => resolve(Buffer.concat(_buf)));
    stream.on('error', (err) => reject(err));
  });
}

module.exports = {
  /**
   * An asynchronous register function that runs before
   * your application is initialized.
   *
   * This gives you an opportunity to extend code.
   */
  register(/*{ strapi }*/) {},

  /**
   * An asynchronous bootstrap function that runs before
   * your application gets started.
   *
   * This gives you an opportunity to set up your data model,
   * run jobs, or perform some special logic.
   *
   */
  bootstrap({ strapi }) {
    /**
     * Temporary workaround for strapi-provider-upload-azure-storage
     */
    strapi.plugins.upload.provider.uploadStream = async (file) => {
      file.buffer = await stream2buffer(file.stream);

      return strapi.plugins.upload.provider.upload(file);
    };
  },
};

Of course this is a workaround but still I fixed my problem with the new version of Strapi v4.2.0
Now I finally allow to Update my custom logo in the Strapi Dashboard.

I hope to help someone that has the same issue
