cypress-file-upload not working

cypress-file-upload plugin was working fine but has stopped working since last week.

Here is the upload command i am using

       cy.fixture(fileName, 'binary')
            .then(Cypress.Blob.binaryStringToBlob)
            .then(fileContent => {
                cy.get('.file-upload').upload(
                    { fileContent, fileName, mimeType: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', encoding: 'utf8' },
                    { subjectType: 'drag-n-drop', force: true },
                );
            });
    })

The error i am getting is

> CypressError: cy.then() timed out after waiting '50000ms'.

Your callback function returned a promise which never resolved.

The callback function was:

function(u){try{var y=(void 0===(F=a)&&(F={}),void 0===(A=j)&&(A={}),Object.assign({},A,F)),g=y.subjectType,h=y.subjectNature,E=y.force,O=y.allowEmpty,P=y.events;return function(e){var t=e.subjectType,o=e.subjectNature,i=e.force,s=e.allowEmpty,a=e.events;if(-1===Object.values(n).indexOf(t))throw new T(f);if(-1===Object.values(r).indexOf(o))throw new T(l);if("boolean"!=typeof i)throw new T(p);if("boolean"!=typeof s)throw new T(d);if(!Array.isArray(a)||!a.every(function(e){return"string"==typeof e}))throw new T(b)}({subjectType:g,subjectNature:h,force:E,allowEmpty:O,events:P}),function(e){var t=e.subject;if(!t||!t[0]||!w[e.subjectType][e.subjectNature](t[0]))throw new T(c)}({subject:e,subjectNature:h,subjectType:g}),function(e,t){(Array.isArray(e)?e:[e]).forEach(function(e){var n=e.fileContent;if(!(t?!n:n)||!e.fileName||!e.mimeType)throw new T(v)})}(t,O),Promise.resolve(function(e){var t=e.validator,n=e.constructor;return Cypress.Promise.all(e.files.map(function(e){var r=e.fileContent,s=e.fileName,a=e.mimeType,u=e.encoding;void 0===u&&(u=function(e){var t={};return t[o.JSON]=i.UTF8,t[o.JS]=i.UTF8,t[o.COFFEE]=i.UTF8,t[o.HTML]=i.UTF8,t[o.TXT]=i.UTF8,t[o.CSV]=i.UTF8,t[o.PNG]=i.BASE64,t[o.JPG]=i.BASE64,t[o.JPEG]=i.BASE64,t[o.GIF]=i.BASE64,t[o.TIF]=i.BASE64,t[o.TIFF]=i.BASE64,t[o.ZIP]=i.BASE64,t[o.PDF]=i.UTF8,t[o.VCF]=i.UTF8,t[e.slice(e.lastIndexOf(".")+1)]}(s));try{return t({fileContent:r,fileName:s,mimeType:a,encoding:u}),Promise.resolve(function(e){var t=e.fileContent,n=e.mimeType,r=e.encoding,o={};return o[i.ASCII]=function(){return Promise.resolve(t)},o[i.UTF8]=function(){return Promise.resolve(t)},o[i.UTF_8]=function(){return Promise.resolve(t)},o[i.BASE64]=function(){return Cypress.Blob.base64StringToBlob(t,n)},o.default=function(){return Cypress.Blob.base64StringToBlob(t,n)},(o[r]||o.default)()}({fileContent:r,mimeType:a,encoding:u})).then(function(e){return n([e],s,{type:a})})}catch(e){return Promise.reject(e)}}))}({files:Array.isArray(t)?t:[t],validator:function(e){return function(e){if(!e||-1===Object.values(i).indexOf(e))throw new T(m)}(e.encoding)},constructor:function(){for(var e=[],t=arguments.length;t--;)e[t]=arguments[t];return new(Function.prototype.bind.apply(u.File,[null].concat(e)))}})).then(function(t){var n;Cypress.log({name:"upload",displayName:"UPLOAD",message:t.map(function(e){return e.name}).join(", "),consoleProps:function(){return{subjectType:g,subjectNature:h,files:t,force:E,allowEmpty:O,events:P}}}),(0,s[(n={subjectType:g,subjectNature:h}).subjectType][n.subjectNature])({window:u,subject:e,force:E,events:P},{files:t})})}catch(e){return Promise.reject(e)}var F,A}

Cypress version ^4.1.0 cypress-file-upload version ^3.5.3

Thanks for reporting this issue. However, cypress-file-upload is not maintained by the Cypress.io team. Seeing as you have already reported the issue on the correct repo for that plugin, I’m going to go ahead and close this issue.

try adding invoke(‘show’) and trigger:

cy.get(‘input[type=“file”]’).invoke(‘show’); cy.get(‘input[type=“file”]’).attachFile(fileName).trigger(‘input’);
