[RPG] Does a bag of holding burst if brought into the space created by Rope Trick

dnd-5emagic-itemsspells

A bag of holding has a special caveat:

Placing a bag of holding inside an extradimensional space created by a Handy Haversack, Portable Hole, or similar item instantly destroys both items and opens a gate to the Astral Plane.

Now, the 2nd level spell Rope Trick says:

(…) At the upper end of the rope, an invisible entrance opens to an extradimensional space that lasts until the spell ends.

The extradimensional space can be reached by climbing to the top of the rope. (…)

Is it safe to bring a bag of holding inside the rope trick extradimensional space?

Best Answer

No the bag will not burst, because Rope Trick is not an item

The key word in the caveat you cite is "item":

Placing a bag of holding inside an extradimensional space created by a Handy Haversack, Portable Hole, or similar item instantly destroys both items and opens a gate to the Astral Plane.

The two examples the text gives are also items.

However, the extradimensional space created by Rope Trick is created by a spell, not an item, and so does not fall under that clause.

There are many spells that generate extradimensional spaces (such as Mordenkainen's Magnificient Mansion)--if the designers intended the Bag of Holding to explode when it entered such spaces, they could have easily made the text refer to any extradimensional space, or used spells as examples.
