error: Module.open is not a function
version: 0.7.8
env: esm

let f = new h5wasm.File(this._fileName, 'r')  // error: Module.open is not a function 

Temporary solution:

Change the file hdf5'hl.js generated by packaging

export class File extends Group {
    constructor(filename, mode = "r", track_order = false) {
        let file_id;  //<< restore
        const access_mode = ACCESS_MODES[mode];
        const h5_mode = Module[access_mode];
        //const file_id = Module.open(filename, h5_mode, track_order);
          //<< restore
        if (['H5F_ACC_TRUNC', 'H5F_ACC_EXCL'].includes(access_mode)) {
            file_id = Module.ccall("H5Fcreate", "bigint", ["string", "number", "bigint", "bigint"], [filename, h5_mode, 0n, 0n]);
        }
        else {
            // then it is an existing file...
            file_id = Module.ccall("H5Fopen", "bigint", ["string", "number", "bigint"], [filename, h5_mode, 0n]);
        }
      // >>
        super(file_id, "/");
        this.filename = filename;
        this.mode = mode;
    }

Can you tell me more about how you encountered the error? Was it in the browser, in a bundled application, etc?

When I import h5wasm from https://cdn.jsdelivr.net/npm/[email protected]/dist/esm/hdf5_hl.js in a browser, I am able to open files so I am not sure how to reproduce the error.
