A long-shot but I made a similar mistake. When you declare performSearch function in the App.js, make sure it has the proper syntax of an arrow function. Maybe it helps some1. ;)

Full Stack JavaScript Techdegree Graduate 22,378 PointsRick is correct. I had the same issue.
found the solution on stack
performSearch needs to be written like:
performSearch = (query ) => {
axios.get(`http://api.giphy.com/v1/gifs/search?q=${query}&api_key=QGx0HYKQgMVMrdvG8nly3aQfAAVUi7q7&limit=24`)
.then(response => {
this.setState( {
gifs: response.data.data});
})
.catch((error) => {
console.log('Error fetching and passing data', error)
});
}
If the function is not defined as a arrow function, you would need to .bind() "this" like
this._handleDelete = this._handleDelete.bind(this);
To avoid it all together, just use the proper arrow function syntax.
I guess you get _this2 becaue it's the second time ''this" pops up in your code. It was the 3rd time in mine and got the _this3

" defined or referenced in this code, but without Markdown formatting, we may not be seeing it correctly.
A link to a workspace snapshot would make replication of the issue far easier.
